Texas Go Math Grade 4 Lesson 13.6 Answer Key Find and Draw Lines of Symmetry

Essential Question

How do you find lines of symmetry?
Answer:
We can find the lines of symmetry if a shape has a Line of Symmetry by folding it. When the folded part settles perfectly on top (all edges should match), then the folding line is a Line of Symmetry.

Activity 1 Find lines of symmetry.

Materials

• isometric and square dot paper
• straightedge

STEP 1 Draw a triangle like the one shown, so all sides have equal length.

Answer:

STEP 2 Fold the triangle in different ways to test for line symmetry. Draw along the fold lines that are lines of symmetry.

Is there a line of symmetry if you fold the paper horizontally?
Answer:
No.

Explanation:

If we fold the paper horizontally there will be no line of symmetry.

STEP 3
Repeat the steps for each polygon shown. Complete the table.

Answer:

In a regular polygon, all sides are of equal length and all angles are equal. What do you notice about the number of lines of symmetry in regular polygons?
Answer:
A regular pentagon has five sides and five lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides.

Mathematical Processes
How many lines of symmetry does a circle have? Explain.
Answer:
There are an infinite number of lines through the center, therefore the circle has an infinite number of lines of symmetry.

Explanation:
When the circle is folded over a line of symmetry, the parts of the circle on each side of the line match up. This means any line that passes through the center of the circle will be a line of symmetry.

ERROR Alert: To avoid errors, you may use a mirror to check for line symmetry.

Activity 2 Make designs that have line symmetry.

Materials

• pattern blocks

Make a design by using more than one pattern block. Record your design. Draw the line or lines of symmetry.

Make a design with 2 lines of symmetry.

Essential Question

How can you identify and draw parallel lines and perpendicular lines?
Answer:
Parallel lines are lines in a plane that always have the same distance apart. Parallel lines never intersect each other. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

Explanation:
$\text{Perpendicular lines }$are lines that meet at right angles.

Parallel lines are always the same distance apart from each other — no matter how far they are extended, they will never meet.

Texas Go Math Grade 4 Lesson 15.1 Answer Key Measurement Benchmarks

Essential Question

How can you use benchmarks to understand the relative sizes of measurement units?
Answer:
benchmarks can be defined as the standard or reference point against which something can be measured, compared, or assessed. Benchmark numbers are numbers against which other numbers or quantities can be estimated and compared.
Benchmarks for Metric Units The metric system is based on place value. Each unit is 10 times as large as the next smaller unit. Below are some common metric benchmarks.

Unlock the Problem

A mile is a customary unit for measuring length or distance. The benchmark shows the distance you can walk in about 20 minutes.

Jake says the length of his bike is about four yards. Use the benchmark units below to determine if Jake’s statement is reasonable.

A baseball bat is about one yard long. Since lake’s bike is shorter than four times the length of a baseball bat, his bike is shorter than four yards long.

So, Jake’s statement __________ reasonable.
Jake’s bike is about __________ baseball bats long.
Answer:
So, Jake’s statement is not reasonable.
Jake’s bike is about 1 baseball bats long.

Example 1 Use the benchmark customary units.

About how much liquid is in a mug of hot chocolate? ____________
Answer:
A mug of hot chocolate is about 8 fluidounces as 1 cup can hold 8 fluid ounces.

About how much does a grape fruit weigh? ___________
Answer:
A grape fruit weighs about 1 ounce as it is comparatively similar to the weight of a pencil.

Example 2 Use the benchmark metric units.

A kilometer is a metric unit for measuring length or distance. The benchmark shows the distance you can walk in about 10 minutes.

Is the length of your classroom greater than or less than one kilometer?
Answer:
The length of my classroom is less than 1 kilometer. As the length of the will not take 10 minutes to walk along the classroom.

Answer:
The distance between Seattle and San Francisco is 680 miles.

Math Talk

Mathematical Processes
Explain why you would use kilometers instead of meters to measure the distance across the United States.
Answer:
I use kilometers to measure the distance across the United States not meters because it takes so many minutes to measure the distance of United States. A kilometer is the distance that a person can travel in 10 minutes. So, it will be better if we measure the distance in kilometers if it is very long.

Texas Go Math Grade 4 Lesson 13.1 Answer Key Lines, Rays, and Angles

Essential Question

How can you identify and draw points, lines, line segments. rays, and angles?
Answer:

Unlock the Problem

Everyday things can model geometric figures. For example, the period at the end of this sentence models a point. A solid painted stripe in the middle of a straight road models a line.

Activity 1 Draw and label \(\overline{J K}\).
Answer:
I have drawn and labeled \(\overline{J K}\).

Explanation:

Math Talk

Mathematical Processes
Explain how lines, line segments, and rays are related.
Answer:
A ray is a part of a line.
A line segment can be a part of a line, ray, or another line segment.

Explanation:

Ray AB = \(\overline{A B}\)

The line CD = \(\overline{C D}\) or line DC = \(\overline{D C}\).
From this we get \(\overline{C D}\) or \(\overline{D C}\).
From the above segment AB = \(\overline{A B}\), segment BA = \(\overline{B A}\)
segment CD = \(\overline{C D}\) and segment DC = \(\overline{D C}\)

Is there another way to name \(\overline{J K}\)? Explain.
Answer:
Yes

Explanation:
Yes, there is a way to name \(\overline{J K}\) by switching the letters, \(\overline{K J}\) and when we are naming a line segment, either point can be named first.

Angles

You can name an angle by the vertex. When you name an angle using 3 points, the vertex is always the point in the middle.
Answer:
We cannot say ∠B here because that could be one of three angles. So we have to use either ∠ABD or ∠ABC, or ∠DBC. We need to remember when we name an angle using 3 points, the vertex is always the point in the middle.

Explanation:

Angles are classified by the size of the opening between the rays.

Activity 2 Classify an angle.

Materials
paper

To classify an angle, you can compare it to a right angle.

Make a right angle by using a sheet of paper. Fold the paper twice evenly to model a right angle. Use the right angle to classify the angles below. Write acute, obtuse, right, or straight.

a.

Answer:
Obtuse

Explanation:
An angle that measures greater than 90° degrees is called an obtuse angle.
