In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
There is no figure to be seen but an isosceles trapezoid will have equal base angles.

180 - 2*52 = 76 both base angles are equal (property of an isosceles triangle) and total angles is 180
