Mathematics Knowledge Answer

The topic of triangles is one of the numerous topics that I review with my ASVAB students in my role as an ASVAB tutor.  I review the different types of triangles based on their angles: scalene, right, and obtuse.  I also review the different types of triangles based on their sides: equilateral, isosceles, and scalene triangles.

On 8/13, I presented a Mathematics Knowledge question.

The question is a geometry question.  It is about triangles.

The questions is:

What triangle has all 3 sides and all 3 angles equal?

  1. Scalene
  2. Right
  3. Isosceles
  4. Equilateral

The triangle that has 3 equal sides and 3 equal angles is called an equilateral triangle.

The correct answer is D. Equilateral

The total number of angles in a triangle is 180 degrees.

Each angle in an equilateral triangle is 60 degrees since the 3 angles are equal.
