## Texas Go Math Grade 1 Lesson 14.2 Answer Key Attributes of Two-Dimensional Shapes

**Explore**

Use two-dimensional shapes. Sort them into two groups. Draw to show your work.

Answer: **The shapes that are shown below diagram.
Explanation:
CURVED:
* For the curved shapes, there are no sides and corners. Those shapes are called circles, ovals, semi-circles.
STRAIGHT:
* For the straight lines, there will be sides and corners(vertices). Those shapes are called square, rectangle, triangle, trapezium etc.
**

FOR THE TEACHER • Have children sort two-dimensional shapes into groups that are curved and straight. Have them draw the shapes to show how they sorted.

Answer: **The groups were sorted below.
Explanation:
The curved shapes are circle, semi-circle, arc, oval.
The straight-line shapes are square, rectangle, triangle, right angle, pentagon, hexagon, rhombus, etc.**

**

Question 10.

**Multi-step** Sofie has 13 shapes. There are triangles, rectangles, and hexagons. Four shapes have 3 straight sides. Two shapes are hexagons. How many shapes are rectangles?

(A) 6

(B) 9

(C) 7

Answer: Option **C** is correct.

**Explanation:
The number of shapes Sofie has=13
The number of 3 straight sides she have=4
The number of hexagons she have=2
Now we need to find out the number of shapes of rectangles.
By math sentence, it will be written as
No. of 3 straight sides+no. of hexagons=4+2=6.
Now we need to subtract 13 and 6=13-6=7.
Therefore, 7 shapes of rectangles are present.**
