Question

(1)Show that
the angles of
equilateral
triangle are 60 each

Answer 1

In equi. triangle

All angles are equal

Let each angle be x

x+x+x=180 (triangle sum prop.)

3x=180

x=180/3

x=60

Hence proved

Answer 2

Answer:

equal sides of a triangle has opposite angle equal

Ok so as we know by the name that equilateral triangle has all sides equal so all 3 angles are equal too.

Now by angle sum property angle a + angle b+ angle c= 180 degrees

3 angle a= 180 degrees (as angles a angle b and angle c are equal)

angle a = 180/3 =60 degrees.

hence all angles are 60 degrees
