It will have two equal base angles of 70 degrees.
56 degrees
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
Vertex angle = 180 - 2(62) = 56 degrees
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
57.5 degrees
56 degrees
20 degrees
If your "53" is in degrees, then the vertex angle is 74 degrees.
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
Vertex angle = 180 - 2(62) = 56 degrees
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
57.5 degrees
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
80 degrees
Each one is 40 degrees.
Vertex angle is 180-53-53 = 74 degrees
