Question

The measure of the vertical angle of an isosceles triangle is twice the measure of each of its base angles.calculate the measure of all the angles of the triangle​

Answer 1

Answer:

in isosceles triangle two sides are equal

so opposite angle of two side are equal

now equal angle be x then verticle angle is 2x

so by angle sum property of triangle

x + x+ 2x = 180°

4x = 180

x= 180 /4

x = 45°

then verticle angle is 90°
