Example 2:How do you calculate the perimeter of an isosceles triangle with two sides of length ‘a’ cm each and a third side of length ‘b’ cm? Solution: Perimeter of an isosceles triangle = sum of its sides Perimeter of an isosceles triangle = (a + a + b) cm ...
An obtuse triangle is a triangle with one interior angle measuring greater than 90 degrees. In geometry, triangles are considered as 2D closed figures with three sides of the same or different lengths and three angles with the same or different measurements. Based on the length, angles, and pr...
A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene. A triangle can be simultaneously right and isosceles, in which case it is known as an isosceles right triangle. ...
All three sides of a scalene triangle are in different lengths. It is a triangle with no sides of equal length and no angles of equal measure. An isosceles triangle has two equal-length sides, an equilateral triangle has three equal-length sides, and an obtuse triangle has one angle ...
Two sides of a polygon are congruent if they have the same length. Triangles with different numbers of congruent sides have different names...
