An equilateral triangle has the same length for each side, and the same angle for each vertex. All triangles have a mathematical property that states that the sum of all three angles in any triangle will equal 180 degrees. Since we know that all angles are the same, and there are three of them, each angle must be 60 degrees. An acute angle is one that is less than 90 degrees, and thus, each of the three angles are acute.

Are all acute triangles equilateral triangles?
No, but all equilateral triangles are acute. Acute: All angles of the triangle are less than 90 degrees. Equilateral: All angles of the triangle are 60 degrees.
What does an acute equilateral triangle look like?
Aren't all equilateral triangles acute??
Which statement about triangles cannot be proved for all triangles?
if a triangle is acute, then the triangle is equilateral
Is an equilateral triangle an acute triangle?
Yes. All equilateral triangles are acute triangles, as they have 3 angles of 60 degrees each, all less than 90 degrees.
Can an acute triangle also be an equilateral triangle?
Yes it can. Every equilateral triangle is an acute one. To put it another way, the family of acute triangles includes all equilateral ones.
