use protractor, or divide isosceles triangle into two right triangles, and use trigonometric functions to find the angles individually (ONLY IF YOU HAVE ALL SIDE LENGTHS CAN YOU DO THIS)

there are three angles on an isosceles triangle
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's 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.
A right angled isosceles triangle!
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
