"WebIn an isosceles triangle, there are two base angles and one other angle. The two base angles are equal to each other. So say you have an isosceles triangle, where only two sides of that triangle are equal to each other. And then you have 36 degrees as one of your base angles. The other base angle will equal 36 degrees too. 36 + 36 + x = 180 degrees " - Determine angles of triangle from the sides
