CBSE - IX - Mathematics - Triangles
Show that the angles of an equilateral triangle are 60 degrees each
By angle sum property we know that the sum of all the angles of a triangle is 1800
We know that all the sides of a triangle are equal.
i.e all the angles of an equilateral triangle are equal.
Let each angle be x.
x + x + x = 1800
3x = 1800
⇒x = 600
Hence the answer.
