##### Geometry: 1,001 Practice Problems For Dummies (+ Free Online Practice)

In geometry, the point in a triangle where the angle bisectors of the triangle intersect is called the incenter. The following practice questions test your skills at finding the incenter of a given triangle.

## Practice questions

Point I is the incenter of triangle CEN. Use the following figure and the given information to solve the problems.

1. If

2. If

is represented by 2c, and

is represented by 2b + c, find the value of b.

1. 26 degrees

The incenter of a triangle is the point where the bisectors of each angle of the triangle intersect. A bisector divides an angle into two congruent angles.

Find the measure of the third angle of triangle CEN and then cut the angle in half:

2. 4

The incenter of a triangle is the point where the bisectors of each angle of the triangle intersect. A bisector divides an angle into two congruent angles.
