1. Quick Start Expectations 1.Fill in planner and (HWRS) HW: SS - p. 37 #3 2.Get a signature on HWRS 3.On desk: journal, HWRS, pencil, pen 4.Warm Up: Complete the WS:SS LS 2.2 Look at the rules for Hats 1 to 5 in the table. Predict how each rule will change Mug’s hat. Then graph.

2. SS Inv. 2.2

8. Hats 1 & 2 – Angles and side measure are exactly the same as Mug’s Hat Hat 3 – same width as Mug’s, but its height is 3 times as long, and the bottom angles have larger measures Hat 4 – the width and height are half as long as Mug’s hat, but the corresponding angles are the same Hat 5 – the width is 2 times as long, the height is 3 times as long, and it has larger angle measures at the bottom

9. Hat 1, 2, and 4 are similar to Mug’s Hat. Same shape Same corresponding angles Sides have been multiplied by the same factor

11. If you choose any two positive numbers a and b that are not equal to each other, the hat made by (ax, by) is not similar to Mug’s Hat.
