Question

Introduction on triangle maths project

Answer 1

Hey mate
Here is your answer

Triangles can be described by the lengths of their sides (equilateral, isosceles, and scalene) or by the sizes of their angles (acute angles, right angles, and obtuse angles).
A triangle is scalene if all of its three sides are different (in which case, the three angles are also different). If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral.
