# Angle Bisector of Base of Isosceles Triangle Calculator

In Isosceles triangle, Angle bisector are the lines that divides the angle into two equal parts with the equal measure. Every triangle has three such lines. All these three bisector lines intersect at a point called as Incenter of the triangle. The bisector of the angle opposite to the base is the altitude and the median. Use this online Angle Bisector of Base of Isosceles Triangle Calculator to find the angle bisector of base from its base and side length.

#### Formula:

Angle Bisector of Base of Isosceles Triangle = √(4a^{2} - b^{2}) / 2
**Where,**
a = Side Length of Isosceles Triangle
b = Base Length of Isosceles Triangle
### Example:

An Isosceles triangle with base length of 12 cm and side length of 8 cm. Find Angle Bisector of Base of Isosceles Triangle.

#### Solution

Angle Bisector of Base of Isosceles Triangle = √(4x8^{2} - 12^{2}) / 2

= 5.2915 cm
