Question

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

50, 45, 130, 25

Answer 1

So triangles have a sum of 180° and in an isosceles triangle, two of the angles are equal. If we have one angle that measures 130°, the other two have to add up to 50°. Since the two are equal, the only answer can be 25°!
