Question

In a truangle adc , dac=dca=30, then fund the relation between ad and ac

Answer 1

It is a isosceles triangle, because these base angles, angle DAC and angle DCA are equal so AD=AC. In isosceles triangle base angles are equal and two sides are equal.

Answer 2

In triangle adc ,dac=dca=30..
in a triangle the sum of interior angles =180
so,adc=120
adc>acd
⇒ac>ad
