Equal Side Lengths

The most distinguishing feature of an isosceles triangle is its two sides being of equal length. This symmetry opens up a world of possibilities in geometric calculations.

Base Angles

In addition to equal side lengths, isosceles triangles have equal base angles. Understanding these angles is crucial for further exploration of their properties.

Area of a Right Isosceles Triangle Formula:

Apply the following formula for the right isosceles triangle. 

Area: B x H x 0.5

H: Height distance from the base to the opposite vertex. 

B: Represents the length of the unequal side.

Practical Example of the Area of a Right Isosceles Triangle:

Follow the Following example to understand the formula practically.

1. An isosceles triangle with a base of 8 units and a height of 6.
2. Add these values into the formula:

Area: 0.5 x 6 x 4 = 12
