Could be a 90-60-30 degree triangle.
so,
60 degrees.
The sum of the angles in a triangle is 180 degrees.
A isosceles triangle
An obtuse triangle

There are three angles in a triangle but to measure them you would use a protractor.
Well a triangle with two congruent sides would be called a isosceles triangle. It has a vertex, two base angles, two legs, and a base.
If two angles of a triangle each measure 55 what is the measure of the third angle?
