- An equilateral triangle is a triangle in which all three sides and all three angles are of equal measurement.
Facts & Information
- When you add all three angles of a triangle, the sum is always 180⁰.
- If we divide 180⁰ by 3, each angle will equally measure 60⁰. Therefore, all angles of an equilateral triangle will always measure 60⁰.
- As all angles of an equilateral triangle are less than 90⁰, it is also classified as a type of acute triangle.
Measuring Equilateral Triangles
An equilateral triangle is defined by having all sides with equal measurements and all angles measuring the same 60⁰.
We can simply find out if a triangle is equilateral by measuring all sides of the triangle using a ruler. If all sides have the same measurements, then it is an equilateral triangle.
Otherwise, we could also use a protractor, which is a tool that we can use to measure angles.
It is usually a flat semicircular form with the angle degrees marked on the curved side.
