This document discusses properties of different polygons. It describes that an equilateral triangle has three equal sides and three equal 60 degree angles. A rectangle has sides that are not equal but angles that are equal, while a square has both equal sides and equal angles. A regular pentagon has both equal sides and equal angles, with each angle measuring 108 degrees. Regular polygons are defined as those with both equal angles and equal side lengths. Regular heptagons and hexagons are also mentioned.

2. See the equilateral
triangle
The angles are equal
The three sides are equal
<ABC=60o , <ACB=60o ,
<CAB=60o

3. RECTAGLE &
SQUARE
In rectangle ABCD
The sides are not equal but
angles are equal.
In the case of square
The sides are equal
The angles are also equal.

4. REGULAR
PENTAGON
In this pentagon
The sides &angles are equal.
Each angle is 1080

5. REGULAR POLYGONS
We can conclude that, polygons like this, with
equal angles and lengths of sides also equal
are called REGULAR POLYGONS
