So the perimeter of the triangle is the sum of all the sides. Once you have the three sides you can determine if it is scalene, isosceles, or ing the distance formula how do i solve this Jessie. Perimeter is nothing but the sum of all the sides of any 2 – dimensional shape. Now it is given that the perimeter of a scalene triangle and isosceles triangle and an equilateral triangle are equal. Some right triangles can be a scalene triangle if the length of the legs of the right triangle is not the same, as shown in the figure. Note: Equilateral Triangle: A Triangle is called equilateral triangle if length of 3 sides of it are equal. In an isosceles triangle opposite angles corresponding to similar sides are equal, and the opposite angle corresponding to different sides is different from the other two angles, as shown in the figure.īut the sum of all the angles remains 180 degrees.Ī scalene triangle is a triangle in which all the lengths of the sides are different w.r.t each other and the measures of all the angles are also different with each other. Types of Triangles - Equilateral, Isosceles, Scalene Very Easy Learning 6.61K subscribers Subscribe 1. If the three sides of a Triangle are entered through the keyboard, write a program to check whether the Triangle is isosceles, equilateral, scalene Triangle. So in an equilateral triangle the measure of all the angles are equal to 60 degrees, as shown in the figure.Īn isosceles triangle is a triangle in which any of the lengths of two sides are equal and the length of the third side is different from the other two sides. So let that measure of one angle be x degrees. In a triangle the sum of all angles is 180 degrees. An equilateral triangle is a triangle in which all the sides of the triangle are equal and the measure of all the angles are also equal.

Scalene isosceles or equilateral
