Question

show that the angles of an equilateral triangle are each 60 degrees ​

Answer 1

$\huge{\boxed{\mathtt{\red{ANSWER}}}}$

By angle sum property we know that the sum of all the angles of a triangle is 180°

We know that all the sides of a triangle are equal.

Let each angle be = x°

x + x + x = 180°

3x = 180°

x = 60°

so, all angles of equilateral ∆ = 60°

Answer 2

Answer:

60 + 60 + 60 =180

Step-by-step explanation:

<A+<B+<C=180°. (the sum of interior angle is 180°)

So, 60+60+60=180°

180°=180°
