Question: what is the difference between an acute triangle and an equilateral triangle?
Answer: For a triangle to be equilateral, it must also have equal angles. ... Angles are either right, which is to say 90 exactly, or obtuse, which is to say greater than 90 and less than 180, or acute, which is to say less than 90. An acute triangle is one in which all three angles are acute. Equilateral triangles are all acute.
