Question

Section B (3x2 = 6) Show that the angles of an equilateral triangle are 60° each. In the given figure, AD = BC and BD = AC, prove that ZDAB = LCBA ​

Answer 1

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.

i.e all the angles of an equilateral triangle are equal.

Let each angle be x.

x+x+x=180

60o

3x = 180

⇒ x = 60

Hence the answer.
