Tasks for Today Warm Up– Properties of Triangles Lesson 4.1/4.2 – Dilations & Similarity Transformations

Warm Up B . SAS - congruence

Labsheet 4.1 with tables

Angle measures stay the same! Side lengths of P’Q’R’S’ are 3 times those of PQRS. Angle measures stay the same!

The rule (x, y) (3x, 3y) shows how coordinates of corresponding points are related under a dilation with center at the origin (0, 0) and scale factor 3.

Use Labsheet 4.2

Look for figures that seem to have same general shape, but different size Check by measuring angles, and comparing corresponding sides.
