What are the properties of the incenter of a triangle?

Step-by-step explanation:

We know that, 'Incenter of a triangle' is:

1. The center of the circle drawn inside the triangle which is tangent to the sides of the triangle i.e. it touches the each side the triangle exactly once.

2. The point of intersection of the three angle bisectors of a triangle, where an angle bisector is a line that splits an angle exactly in half.

Hence, the properties of the incenter are:

1. it is the center of the circle drawn inside the triangle.

2. It is the point of intersection of the three angle bisectors of a triangle.

3. Moreover, it is always located inside the triangle.

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
