Question

In a triangle ABC, AB = AC and <A= 70°, find the angels, <B and <C.
​

Answer 1

Answer:

if AB=AC then it will be an isosceles triangle , so angle b = angle c , then by using angle sum property we can say that angle a + angle b +angle c = 180° , since angle b = angle c , 180 - 70 =110° . now we can say that 2angle b = 110°, angle b = 110°/2 = 55° and angle b =55° , angle = 55° and angle a = 70° . u can check by putting these values to respective places and do angle sum property
