Answer 1

1. A polygon is any shape with straight edges, so A, C and D.

2.

The 4 inside angles need to equal 360 degrees.

360 - 248 = 112

112/2 = 56

Each top corner = 56 degrees.

X = 56 / 2 = 28

X = 28

3. A regular polygon has all equal sides and angles, this would be figure B.

4. A pentagon has 5 sides.

5. Hexagon ( 6 sides), pentagon ( 5 sides), and decagon ( 10 sides).
