Calculating distance between points and using it to prove isosceles, scalene, or equilateral triangles, congruent segments, or perimeter of a figure. Included: A 16 problem Worksheet An 8 problem Homework Two versions of a short quiz/exit ticket - 2 questions calculating perimeter and finding out whether segments are congruent using distance formula Answer keys included

Proving triangles congruent using SSS, SAS, and ASA Postulates. 5 fill in the blank proofs and 5 full proofs with key. Parallel lines, definition of midpoint and angle bisector, etc. mixed with triangles. Great proof practice.

Perfect Worksheet for naming corresponding sides, angles, and triangles in corresponding order. Includes algebra and coordinate problems. This is a good length for a homework assignment or assessment after the lesson.
