Question

If three angles of a triangle are congruent then it's three sides also are congruent write the proof of this corollary

Answer 1

Answer:

angle A = angle B = angle C (given)

Now,angleA +angle B + angle C = 180degree ( angle sum property of a triangle)

= each angle is 60 degree .

so , Triangle ABC is an equilateral triangle ..

=> AB = BC =AC { sides of equilateral triangle are equal}

Hence, proved...
