Question

Q6. State True or False
1. The sum of angles of an equilateral triangle is 60
2. Square is an example of regular polygon​

Answer 1

Answer:

a)False , sum of angles is 180°

b)True

Answer 2

Answer:

1.true

2.true

Step-by-step explanation:

1.we know the property that angles opposite to equal sides are equal. Now, we know that the angle sum property of a triangle states that the sum of all the angles of a triangle is equal to 180∘. So, each angle of an equilateral triangle is 60∘. Hence proved.

2.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.
