Question

triangle abc is an isosceles triangle . if ab=ac and triangle abc=65degree ,find triangle bca and triangle cab​

Answer 1

Answer:

we know that isosceles have some properties one properties is two side are equal and one side is different in isosceles triangle and opposite side are equal also.

so we have,

ab=ac equal sides and different side is bc

and angle b and c are equal and angle is different.

we have,

angle b=65°

then angle c=65°

The sum of all angle of triangle is 180°

a+b+c=180°

a+65°+65°=180°

a=180°-130°

a=50°

I hope it is useful for you!
