Since an isosceles triangle has two equal angles, and the total of the three angles of a triangle is 180 degrees, the remaining two angles must be equal and sum up to 100 degrees (180 - 80 degrees).
Dividing 100 degrees between two equal angles gives 50 degrees for one of the other angles.
Therefore, one of the other angles is 50 degrees.
An isosceles triangle has only one angle of 80. What is the measurement in degrees of one of the other angles?
