Question

In an isosceles triangle ABC, angle A = angle C = 45 degree, then angle C​

Answer 1

Answer:

Angle C = 90°

Step-by-step explanation:

A+B+C = 180°

45° + 45° + C = 180°

C = 90°

Answer 2

Answer:

isosceles traingle=2 sides equal

=angle A= angle C = 45 degree

= angle A=45 degree

angle A+angle B+angleC=180 degree (angle sum property of a traingle)

= 45 degree+45 degree+ angle C =180 degree

=90 degree+ angle C =180 degree

= angle C= 180 degree - 90 degree=90 degree

=angle C =90 degree
