Question

10.classify these polygons by number of sides. all of them are

1. circle any polygons that are convex. then, draw a face inside the polygon with all congruent angles

Explanation:

Step1: Identify polygon 1

The first polygon has 6 sides, so it is a hexagon.

Step2: Identify polygon 2

The second polygon has 5 sides, so it is a pentagon.

Step3: Identify polygon 3

The third polygon has 6 sides, so it is a hexagon.

Step4: Identify polygon 4

The fourth polygon has 5 sides, so it is a pentagon.

Step5: Determine convex polygons

A convex polygon has all interior angles less than 180 degrees. The first and fourth polygons are convex.

Answer:

1. First - hexagon, Second - pentagon, Third - hexagon, Fourth - pentagon
2. Convex polygons: First and fourth (circle them as required); For drawing a face inside the polygon with all congruent angles, the first polygon (regular hexagon) has all congruent angles, draw a face inside it as required.
