Equilateral, Isosceles, and Scalene Triangles Worksheets

Triangles are an essential part of geometry, and understanding their different types is crucial for students to grasp complex mathematical concepts. In this article, we will delve into the world of triangles, focusing on equilateral, isosceles, and scalene triangles.

What are Equilateral, Isosceles, and Scalene Triangles?

A triangle can be classified based on the lengths of its sides or the measurements of its angles. An equilateral triangle has three equal sides, while an isosceles triangle has two equal sides. On the other hand, a scalene triangle is a triangle with three different side lengths.

Scalene Triangles

A scalene triangle is a type of triangle that has all three sides of different lengths. This means that each side of the triangle has a unique measurement. The angles in a scalene triangle are also acute and add up to 180 degrees.

Here's a comparison between equilateral, isosceles, and scalene triangles:

| Type | Sides | Angles |

| --- | --- | --- |

| Equilateral | Equal | Equal |

| Isosceles | Two equal, one unequal | Two equal, one unequal |

| Scalene | Three different | Acute, adding up to 180 degrees |

Properties of Scalene Triangles

Scalene triangles have some unique properties. The total sum of all interior angles in a scalene triangle is always 180 degrees. This means that the angles A, B, and C also have different measurements.

Here's an illustration of a scalene triangle:

Examples and Solutions

To help you better understand scalene triangles, we will provide examples with solutions for finding the area and perimeter of these triangles. We will also discuss how to identify scalene triangles using the distance formula and how to determine their perimeter.
