Yesterday I presented a question on an isosceles triangle. If one of the equal angles in an isosceles triangle measures 35°, what is the measure of the vertex angle? Do you know the answer to this question? As an ASVAB tutor, I remind my students that triangles are an important part of the Mathematics Knowledge section of the ASVAB. An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles. The sum of the 3 angles in a triangle equals 180 degrees. If one of the equal angles is 35°, the other equal angles is 35°. The sum of those 2 angles is 70°. To find the measure of the third angle, subtract 70° from the total of 180°
180° – 70° = 110°. The measure of the missing angle is 110°.
