A polygon which has all its sides of same length and allits angle of equal measures is dubbed a constant polygon.

You are watching: An equilateral triangle is a regular polygon

Examplesof regular polygon:

In the adjoining number of an equilateral triangle alphabet thereare 3 sides i.e., AB, BC and CA space equal and also there room three angle i.e., ∠ABC, ∠BCA and also ∠CAB are equal.

Therefore, an equilateral triangle is aregular polygon. In the adjoining figure of a square ABCD there room foursides i.e., AB, BC, CD and also DA are equal and there are four angles i.e., ∠ABC, ∠BCD, ∠CDA and also ∠DAB areequal.

Therefore, a square is a consistent polygon. In the adjoining number of a regular pentagon ABCDE thereare 5 sides i.e., AB, BC, CD, DE and also EA are equal and there are five anglesi.e., ∠ABC, ∠BCD, ∠CDE, ∠DEA and ∠EAB areequal.

Therefore, a consistent pentagon is aregular polygon. Irregularpolygon:

A polygon which has all its sides of unlike length and also allits angle of unequal measures is referred to as an rarely often, rarely polygon.

Examplesof rarely often rare polygon:

In the adjoining number of a scalene triangle alphabet there arethree political parties i.e., AB, BC and CA room unequal and also there space three angles i.e., ∠ABC, ∠BCA and also ∠CAB room unequal.

Therefore, a scalene triangle is an rarely often rare polygon. In the adjoining number of a rectangle ABCD there are foursides i.e., AB, BC, CD and DA where the opposite sides room equal i.e., ab = CDand BC = AD. So, all the sides are not equal to each other.

Similarly, among the four angles i.e., ∠ABC, ∠BCD, ∠CDA and ∠DAB wherethe the contrary angles room equal i.e., ∠ABC= ∠CDA and also ∠BCD= ∠DAB. So, every the angles are not equal to every other.

Therefore, a square is an irregularpolygon. In the adjoining number of an rarely often, rarely hexagon ABCDEF thereare 6 sides i.e., AB, BC, CD, DE, EF and also FA are equal and also there space sixangles i.e., ∠ABC, ∠BCD, ∠CDE, ∠DEF, ∠EFA and ∠FAB are equal.

Therefore, an rarely often, rarely hexagon is anirregular polygon.
