Triangles Equilateral
An equilateral triangle is a triangle in which all three sides are the same length. This means that the angles in an equilateral triangle are all 60 degrees.
1. Isosceles Triangle:
An isosceles triangle is a triangle that has two sides of equal length. These two sides are called the base and the height. The third side is called the length. An isosceles triangle has two angles that are also equal in size. These two angles are called the base angles.
2. Equilateral Triangle:
An equilateral triangle is a triangle with all three sides equal in length. This means that the angles between the sides are also 60° each.
3. Scalene Triangle:
A scalene triangle has all sides of different lengths and all angles of different sizes.
An Equilateral Triangle Is An Isosceles Triangle?
No, an equilateral triangle is not necessarily an isosceles triangle.
How to Identify an Equilateral Triangle?
An equilateral triangle is a triangle with all three sides of the same length.
Identifying Equilateral Triangles
An equilateral triangle has three equal sides and three equal angles. To identify an equilateral triangle, draw a line connecting the three vertices. If all the angles are 60°, the triangle is equilateral.
How to Identify the Scalene Triangle?
The scalene triangle has three unequal sides and no two angles are equal.
Type of Angle to Determine a Triangle
We can use an angle to determine a triangle if we know the measure of two angles and the measure of the third angle is different than the other two angles.
