Question 1.

A closed plane figure with all sides congruent and all angles congruent is called a ____. (p.410)

Answer:

We know that,

A closed plane figure with all sides congruent and all angles congruent is called a “Regular Polygon”

Hence, from the above,

We can conclude that

The term that is suitable for the given statement is: Regular Polygon

Question 2.

Line segments that have the same length or angles that have the same measure are ___. (p. 410)

Answer:

We know that,

Line segments that have the same length or angles that have the same measure are “Congruent”

Hence, from the above,

We can conclude that

The term that is suitable for the given statement is: Congruent

Hence, from the above,

We can conclude that

The given triangle is an “Equilateral Triangle” and an “Acute Triangle”

Question 6.

Answer:

The given triangle is:

Now,

From the given triangle,

We can observe that

Out of the three angles, two angle measures are the congruent

All the angle measures are not less than 90°

Hence, from the above,

We can conclude that

The given triangle is an “Isosceles Triangle” and an “Obtuse Triangle”

**Classify the quadrilateral in as many ways as possible. Write quadrilateral, parallelogram, rectangle, rhombus, square, or trapezoid.** TEKS 5.5.A

Question 7.

Answer:

The given quadrilateral is:

Now,

From the given quadrilateral,

We can observe that

There are only 1 pair of parallel sides

Hence, from the above,
