Types of triangles based on the sides: are; scalene triangle, isosceles triangle and equilateral triangle. What is a scalene triangle? A triangle with all three sides of varying lengths is a scalene triangle. As all the three sides are of distinct lengths, the three angles will also be diffe...
Frequently Asked Questions What is an equiangular triangle? What are the different types of triangles based on angles? What is an isosceles triangle? What is the semi-perimeter of a triangle? Are all equilateral triangles isosceles triangles?
The sum of the interior angles of a triangle is always 180 degrees. There are different types of triangles based on their sides and angles. Triangles can be classified as equilateral, isosceles, and scalene. An equilateral triangle has all three sides equal in length. An isosceles triangle has...
