Question

1. choose the correct answer.

a polygon in which any of its diagonals contain points in the exterior of the polygon is called a(n)____
polygon
interior angles
convex polygon
concave polygon

1. choose the correct answer.

the common endpoint of two sides of a polygon is called a(n)____
diagonal of a polygon
convex polygon
regular polygon
vertex of a polygon

Explanation:

• For question 5: A concave polygon has diagonals that contain points in the exterior of the polygon. A convex polygon has all diagonals inside. Interior angles are angles inside the polygon, and just "polygon" is too general.
• For question 6: The vertex of a polygon is the common endpoint of two sides. A diagonal connects non - adjacent vertices. A convex polygon is a type of polygon based on the position of diagonals. A regular polygon has all sides and angles equal.

Answer:

1. concave polygon
2. vertex of a polygon
