Translating on a Coordinate Plane 6 Sections on graph paper (3 coordinate planes on front and 3 on back)
A’ = A Prime (the new point) (image) Example 1: Translate A (3,-2) (Pre-image) 3 units to the left and 4 units down. A(3,-2) A’(0,-6) A A’
Example 2: Translate Point B (-4,-5) 2 units to the right and 1 units up. B (-4,-5) B’(-2,-4) B’ B
Example 3: Translate Segment B(-2,1) C (2,1) 4 units to the right and 2 units down. B (-2,1) C (2,1) B’(2,-1) C’(6,-1) B C B’ C’
Example 4: Translate Triangle QLU 4 units to the left and 2 units up. Q(1,3) L(5,1) U(0,-1) Q’(-3,5) L’(1,3) Q’ U’(-4,1) L’ Q L U’ U
Translations Example 5: Translate Triangle ABC 3 units right and 1 unit left. A(–3, 4) A'(0, 3) B(–4, –1) B'(–1, –2) C(–2, 1) C'(1, 0) Quick Check
Example 6: Translate Quadrilateral ABCD 2 units to the left and 6 units down. A(-1, -5) B(0, -3) C(3, -2) D(4, -4) A(1, 1) B(2, 3) C(5, 4) D(6, 2)
