4.9
Learning Target: I can identify and solve for missing sides of similar triangles. I can prove slope using similar triangles.
Background Information - Similarity
DESMOS - Similar triangles and slope
Group Task 2 - Prove that slope is the same no matter the points on the graph. Show your proof as many ways as you can, including using triangle, graphs, equations, and numbers.
Mastery Check - on a piece of graph paper, draw a graph of a line. Use colors, numbers, triangles, and words to prove that any two points can be used to find slope using similar triangles.
