In an isosceles triangle, the base angle is 44 degrees. Find the angle at the vertex.

In an isosceles triangle, the angles at the base are equal, which means that the second angle at the base of a given triangle is 44 °.

The angles of a triangle add up to 180 °.

Then the angle of an isosceles triangle at its apex is equal to:

180 – (44 + 44) = 180 – 88 = 92 °.

Answer: 92 °.
