One angle of an isosceles triangle measures 130°. Which other angles could be in that isosceles triangle?

Question

Find missing angles in triangles

Answer 1

There are 180º in a triangle.

The base angles in an isosceles triangle are equal.

The base angles cannot be 130º each because 130+130=260 which exceeds 180.

Therefore the third (top) angle must be 130º.

180-130=50º left for the two equal base angles

50/2=25º for each of the base angles
