### Transcript

• 1. Aim: What are translations? MB43 2/24/09 Lomas Do Now: Reflect Δ ABC over the line y=x Reflect P(5,2) over the line x=3 (Hint: do the graph) 1) 2) HW Review: 7, 13, 27 A B C HW: Read 560-572 Do 572-5 #21-25, 29-37odd
• 2. Aim: What are translations? MB43 2/24/09 Lomas Write a description of what you think a translation is (full sentence) HW: Read 560-572 Do 572-5 #21-25, 29-37odd
• 3. Aim: What are translations? MB43 2/24/09 Lomas Function Rule for Translations: P(x,y) P'(x+a, y+b) T a,b HW: Read 560-572 Do 572-5 #21-25, 29-37odd
• 4. Translate the triangle with vertices: (-3,2),(3,4), & (-3,-5) by T 3,5 Translate the point defined by (3,-5) by T -4,1 The image of point (3,-2) is (5,8), find the translation. Translate the triangle with vertices: (-3,4),(-4,2), & (-2,4) by <1,-3>. Translate the triangle with vertices: (-4,-3),(-4,-4), & (-3,-4) by (x,y) -> (x + 1, y + 4). 1) 2) 3) 4) 5) 7) Find the translation that maps (0,-2) to (4, -6). A translation maps the origin to (3,-6) find the image of (-2,4) under the same translation. 6) Aim: What are translations? MB43 2/24/09 Lomas 8) A translation maps (0,3) to (-3,1) find the image of (2,5) under the same translation. HW: Read 560-572 Do 572-5 #21-25, 29-37odd
• 5. Aim: What are translations? MB43 2/24/09 Lomas HW: Read 560-572 Do 572-5 #21-25, 29-37odd
