Yesterday I presented a Mathematics Knowledge question about the measure of the degrees in an isosceles triangle. Triangles is one of the subtopics that I cover in my ASVAB prep course’s review of Mathematics Knowledge. Make sure you know the different types of triangles, Pythagorean theorem, and rules on the angles of triangles. Knowing more about triangles can help improve your ASVAB math score.
If one of the equal angles of an isosceles triangle is 30 degrees, what is the measure of the vertex angle?
If one of the equal angles of an isosceles triangle is 30 degrees, what is the measure of the vertex angle?
Did you know how to figure out the measure of the vertex angle?
An isosceles triangle has 2 equal sides and 2 equal angles.
If one of the equal answers is 30 degrees, the other equal angle is 30 degrees.
The sum of the angles of a triangle equals 180 degrees.
30 + 30 = 60
180 – 60 = 120 degrees.
The vertex angle measures 120 degrees.
