Agenda Wednesday, October 10, 2018 Please enter the room quietly place backpacks under the screen. Be seated with all necessary materials, prepared and ready for instructions before the tardy bell rings. You will need your IM workbooks today. Unit 2 Lesson 10. SLOPE. Please open your books to Page 64. Common Core Standards 8.G.3 Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. 8.G.4 Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

Discuss how Triangle ABC and Triangle A’B’C’ are similar.

Describe why the following two triangles are similar: Page 64 Describe why the following two triangles are similar: Triangle ABC And Triangle CDE

After completing the table, describe: Page 64 After completing the table, describe: How do the slopes compare? How you know three triangles are similar? 3 ÷ 4 = 3/4 3 4 6 ÷ 8 = 6/8 6 8 1.5 ÷ 2 = 1.5/2 1.5 2

Which lines have positive slopes? Which lines have negative slopes? Which line has the steepest slope? Are any two lines shown parallel?

There are four types of slope There are four types of slope. Can you describe what characteristic(s) each type of line has?

Can you identify the mistake that was made in calculating the slope? rise run

“Cool Down” Which line has a slope of 1? Which line has a slope of 2? Which line is steeper?
