20 degrees
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
120 degrees.
These are the degrees of each angle. It is a right triangle, and it also is an isosceles triangle.
40 degrees each
135 degrees.
20 degrees and the two equal angles will be 80 degrees each
80 degrees.
A isosceles right angle triangle will have 2 equal interior angles of 45 degrees and 1 angle of 90 degrees with its largest exterior angle being 180 -45 = 135 degrees.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
It is an isosceles triangle
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
The three interior angles measure 45, 45 and 90 degrees.
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
That's an isosceles triangle.
A right triangle. Also an isosceles triangle.
They are all 60 degrees.
