We worked on two review sheets:

For the “Angles on Triangles” worksheet, students were reminded about the direction to *give the reason(s) used to solve the problem. *(The (s) means it may be only one or more than one reason used for a problem!) Basically, your options of reasons are: Triangle Sum Thm, Exterior Angle Thm, Isosceles Triangle Thm (All learned on Friday 11/18), Vertical Angles Thm, Def. of Linear Pair. Show your work, and label it with your reasons!

For “Proving Triangles Congruent” the front is basically like a lot of the Warm-Up problems for “excerpts from flow-chart proofs.” Use the information given (Put it in a box with the word “Given” underneath it) and say something that follow from it. Hint: Reasons on the front (not necessarily in this order) are: Def. of Midpoint, Def. of Bisect, Alt. Int <‘s Thm, Converse of the Alt Int <‘s Thm.

On the back, use other Triangle congruence proofs in your notes as guidance for these problems.
