All equilateral triangles are isosceles?
A. True
B. False

Yes, all equilateral triangles are also isosceles.

Step-by-step explanation:

An isosceles triangle has at least two sides of the triangle of equal measure and the two base angles are equal in degree measure. By definition all sides of an equilateral triangle are equal in length and all angles are equal in degree measure.

Using this info, I will say yes, all equilateral triangles are also isosceles. The correct answer would be A.) True.
