Mathematics Knowledge Question

One of the topics I cover in Mathematics Knowledge is the topic of triangles.  In working as an ASVAB tutor, in my review of triangles, I review the different triangles based on their angles, different triangles based on their sides, Pythagorean theorem, and common right triangles.

Today I present 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

Do you know what this type of triangle is called?

I will present the answer and explanation in two days.
