A triangle has 2 angles that measure 60°. What kind of triangle is it?
QveST [7]
The correct answer to your question is an equilateral triangle. this is because all triangles must equal 180 degrees,, and if you already have two 60 degree angles then youre only 60 degrees away from 180. this means that every angle of your triangle is going to equal 60 degrees, and when all angles of a triangle are the same, then it becomes an equilateral triangle. this could also be considered an acute triangle since all angles are less than 90 degrees.
