Answer 2

Answer:

Regular polygon:

A polygon which has all its sides of equal length and all its angles of equal measures is called a regular polygon.

Examples of regular polygon:

In the adjoining figure of a square ABCD there are four sides i.e., AB, BC, CD and DA are equal and there are four angles i.e., ∠ABC, ∠BCD, ∠CDA and ∠DAB are equal.

Therefore, a square is a regular polygon.

In the adjoining figure of a regular pentagon ABCDE there are five sides i.e., AB, BC, CD, DE and EA are equal and there are five angles i.e., ∠ABC, ∠BCD, ∠CDE, ∠DEA and ∠EAB are equal.

Therefore, a regular pentagon is a regular polygon.

Irregular polygon:

A polygon which has all its sides of unequal length and all its angles of unequal measures is called an irregular polygon.

EXAMPLES OF IRREGULAR POLYGON:

In the adjoining figure of a scalene triangle ABC there are three sides i.e., AB, BC and CA are unequal and there are three angles i.e., ∠ABC, ∠BCA and ∠CAB are unequal.

Therefore, a scalene triangle is an irregular polygon.
