(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
It is an isosceles triangle
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
You are an isosceles triangle.
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
It is possible if neither of the angles in the triangle measures to 60 degrees
An isosceles right angled triangle
40 degrees each
An isosceles triangle has two equal angles.
