Answer 2

‪Literally speaking, lateral means side and equi refers to equality. Therefore the meaning of equilateral is equal sides. A triangle in which its three sides that are equal in length is called an equivalent triangle. An equilateral triangle also has three congruent sides. With this, we can also say that all three sides have the same measurement when it comes to their length. Taken that all sides are equal, then that triangle is considered an equilateral triangle. ‬
