Pythagorean Theorem Power Point Presentation by Mark Robuck
This is a Power Point presentation by Mark Robuck on the Pythagorean Theorem. There are 20 slides in the presentation. This covers where the name came from, a basic proof, how to use the formula, and Pythagorean triples.
Congruent Triangles
Triangles:48 slide power point includes defining and classifying triangles. Presentation on how triangles can be found congruent (SSS, ASA, SAS, AAS and HL) and why SSA does not work. Four proofs on congruent triangles and four proofs using CPCTC. All proofs have animated statements and reasons, you control when they are shown. All sides can be edited to fit you specific needs.

Law of Sines
Fun presentation on the Law of Sines. Includes ASA, SAA, and SSA (ambiguous case). Includes visuals, example problems, definitions of new words, and a link to a Blooket game. Also includes the formula for calculating the area of an oblique triangle. Very easy to edit to make modifications for your class.I split this into three different lessons that were 50 minutes each. The first lesson was an introduction to Law of Sines with the ASA and SAA cases. The second was focused on the ambiguous case
