regular polygon

Answer 1

Based on your descriptions, here are the correct terms for each statement:

1. A polygon that has an interior angle greater than 180° is a **concave polygon**.
2. A polygon that has no interior angles greater than 180° is a **convex polygon**.
3. A hexagon in which all angles measure 120° is an example of an **equiangular polygon** (it could also be classified as a **regular polygon** if all sides are of equal length).
4. An octagon in which all angles measure 135° and all sides are 6 cm long is an example of a **regular polygon** (since it has equal sides and equal angles).
5. An angle inside a polygon is an **interior angle**.

So the completed answers are:
1. Concave polygon
2. Convex polygon
3. Equiangular polygon (or Regular polygon if all sides are also equal)
4. Regular polygon
5. Interior angle
