Question

Answer 1

Answer: 8 congruent sides and 8 congruent Angles

Explanation:

Answer 2

A regular octagon is a bidimensional figure with eight sides and eight vertices. The words "regular" refers to the equivalence between sides, that is, all sides have the same length.

So, a regular octagon can be described as

• A figure with eight equal sides.
• A figure with eight vertices.
• A polygon.
• A symmetric figure.

The equivalence between sides makes the regular octagon symmetric. Additionally, this figure is a polygon, because it has 8 sides which enclose a region.
