Question

If p, q and r are the angels of an equilateral triangle, p=q=r

Answer 1

Answer:

60

Step-by-step explanation:

In a equilateral triangle all the angles are same

The sum of angles of a triangle is 180 degree

so just divide 180 by 3

Answer 2

Yes,

In the equilateral ∆PQR, let ∠PQR = ∠PRQ = ∠RPQ = x°. Therefore, 3x° = 180° as the sum of the three angles of a triangle is 180°.

Therefore, x° = 180°3

⟹ x° = 60°.

Thus, each angle of an equilateral triangle is 60°.

1. ∠QPR = ∠PQR  ( Angles opposite to equal sides QR and PR.  )

2. ∠PQR = ∠ PRQ.  ( Angles opposite to equal sides PR and PQ.

)

3. ∠QPR = ∠PQR = ∠ PRQ. (From statement 1 and 2)  

(Proved).
