Question

Determine all angles of an equilateral triangle :D​

Answer 1

Answer:

In the equilateral ∆PQR, let ∠PQR = ∠PRQ = ∠RPQ = x°. Therefore, 3x° = 180° as the sum of the three angles of a triangle is 180°. ⟹ x° = 60°. Thus, each angle of an equilateral triangle is 60°.

Answer 2

Answer:

sum of the three angles of any triangle is 180°

in equilateral triangle three angles are equal

so each angle is 180°/3=60°
