If we have a triangle which is obtuse then the in center of a triangle is located in the triangle’s interior.

The triangle is Acute Triangle then also it is located in the triangle’s interior.

Now we will see How to Find the Incenter of a Triangle?

For finding the in center of a triangle we have to follow some of the steps:

Step1: The in center of a triangle is equal distance from all the sides of a given triangle.

Step2: Then we have to find the Cartesian coordinates of the in center, where the vertices of a triangle are:

(x

_{1}, y

_{1}), (x

_{2}y

_{2),}(x

_{3}y

_{3}),

Then the length of a triangle is given by,

(

__ax__

_{1}__+ bx__

_{2}__+ cx__,

_{3}__ay__

_{1}__+ by__

_{2}__+ cy__

_{3}),(a + b + c a + b + c)

How to find the in center of a triangle, we see it with the help of example?

Example: Find the in center of a triangle?

Solution: we have to follow the above steps for finding the in center of a triangle.

We have to inscribe a circle in a triangle.

Following above steps we get ‘I’ is the in center of a triangle. The three angle bisector is known as in center of a triangle.

Triangle is a packed or closed figure which is consists of three line which is linked end to end is known as triangle. A triangle is a type of a Polygon. There are different types of properties which are:

Triangles have vertex, base, altitude, median, area, perimeter, interior angles, and exterior angles.
