### 3.7 Points of Concurrency

3.7 and 3.8 Review Points of Concurrency powerpoint

3.7 and 3.8 Review Points of Concurrency pdf In this lesson you will

● Review how to construct the incenter, circumcenter, and orthocenter of a triangle

● Make conjectures about the properties of the incenter and circumcenter of a triangle

You can use the constructions you learned in this chapter to construct special segments related to triangles.

In this lesson you will construct the angle bisectors and altitudes of a triangle, and the perpendicular bisectors of a triangle’s sides.

After you construct each set of three segments, you will determine whether they are concurrent.
