**Monday, Oct. 2** – Students will be able to determine if two triangles are congruent using congruence postulates.

Agenda:

Collect/check/go over practice work from Friday before break.

Remind students about USA test prep assignment

**Tuesday, October 3** – Students will be able to prove if two triangles are congruent using the triangle congruence postulates.

Agenda:

Continued practice on using the triangle congruence postulates

Introduction to proofs

**Wednesday, October 4** – Students will be able to formally prove that two triangles are congruent.

Agenda:

Continued proofs practice

-students will be paired up and given proofs to work.

– team that completes the most proofs accurately will earn bonus points on the next test (1st, 2nd, & 3rd place groups)

Skills check on proofs.

**Thursday, October 5** – Students will be able to find the centroid of a triangle by constructing the medians of the triangle.

Agenda:

Students will construct the medians of various triangles to discover that they always meet in the same spot.

After the medians are constructed, students will measure the line segments created to discover additional properties of the centroid

**Friday, October 6** – Students will be able to demonstrate a minimum of 75% mastery on triangle congruence, centroids, and proofs.

Agenda:

Questions and answers about any topic from the week.

Quiz on triangle congruence, centroid, and proofs

Practice work on all topics presented so far in this unit.
