Question

1. choose the correct answer.

a(n)____polygon is a polygon that is equiangular but not equilateral, or equilateral but not equiangular, or neither equiangular nor equilateral.
regular
convex
concave
irregular

1. choose the correct answer.

a(n)____polygon is a polygon in which any of its diagonals contain points in the exterior of the polygon.
regular
convex
irregular
concave

Explanation:

• For question 11:
• A regular polygon is both equiangular and equilateral.
• A convex polygon is defined by having all interior angles less than \(180^{\circ}\) and no diagonals outside the polygon (not related to the equiangular - equilateral condition here).
• A concave polygon is about the position of diagonals (not directly about equiangular - equilateral).
• An irregular polygon is one that is either equiangular but not equilateral, or equilateral but not equiangular, or neither.
• For question 12:
• A regular polygon has all sides and angles equal (not about diagonal - exterior point relation).
• A convex polygon has all diagonals inside the polygon.
• An irregular polygon is about side - angle equality (not diagonal - exterior point relation).
• A concave polygon is defined as a polygon in which any of its diagonals contain points in the exterior of the polygon.

Answer:

1. irregular
2. concave
