They're the 'base angles'.
Vertex angle
The angle that is not congruent to the base angles of an isosceles triangle is called the "vertex angle." In an isosceles triangle, the vertex angle is formed by the two equal sides, while the base angles are the angles opposite the equal sides.
The base angles of an isosceles triangle are called the base angles. In an isosceles triangle, two sides are of equal length, and the angles opposite these sides are also equal. This means that the base angles are congruent. The third angle, which is the vertex angle, is located opposite the base.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
To find the equal angels, base angles, of an isosceles triangle and you know the vertex angle, 180-vertex angle and then divide by two.

The two angles that are not the isosceles vertex are equal.

An isosceles triangle has at least two equal angles, known as the base angles, which are opposite the two equal sides. The third angle, called the vertex angle, is different unless the triangle is equilateral. The sum of all angles in any triangle, including an isosceles triangle, is always 180 degrees.
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
The base

130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
