More Practice with Circumcenters and Incenters

• ​The CIRCUMCENTER is the intersection of the three perpendicular bisectors of a triangle.

• The circumcenter is equidistance from the VERTICES, which means BP, AP and CP are congruent.

​

​Let's answer questions #1-6 on pg 13.

Here are the answers to #1-6. If you didn't record your answers in your packet please complete it before moving on.

​

​Complete #7...

Note: Since P is the circumcenter we know that E is a midpoint and BE is congruent to CE.

​Let's try #7

Complete #8.

Note: Since P is the circumcenter ​it is equidistant from the vertices of the triangle which means BP, CP and AP are congruent.

​Let's try #8

​Complete #19.

Note: Since K is the incenter we know that EK, FK and DK are all angle bisectors!

(Check answer on next slide)

​Let's try #19

​Complete #20.

Note: Since K is the incenter we know that it is equidistant from the sides of the triangle, so GK, HK and IK are congruent.
