In an isosceles triangle, two of the angles are equal. And, a triangle’s three angles add up to 180. So: if an isosceles triangle has one angle measuring 38 degrees, it also has another angle measuring 38 degrees. To find the measure of the third angle, subtract from 180 the sum of the two other angles. Like this: 180 - (38+38). Then solve it: 180 - 76 = 104. So: the angles are 38 degrees, 38 degrees, and 104 degrees.
