1. Do Now Draw a triangle at points a(2,0) b(-3,3) and c(-4,2) on the coordinate plane. 1. translate the triangle 2 units right and 2 units down 3. reflect the original object across the Y axis 3. rotate the figure 90 degrees

2. What should I learn today? Objective: SWBAT use previous knowledge of symmetry and coordinates to describe and draw a rotation, translation, and reflection Standard: 6.G.3- Determine if two shapes are congruent by motions or series of motions, predict the results of transformations on unmarked planes and draw the transformed figure. Essential Question: what is the difference between reflection, translation, and rotation? Explain

3. Math Drill Please clear everything off your desk Leave your paper face down until I say go Write your name on the back of the paper You will have 5 minutes to complete the drill You must remain at zero the entire time! If you finish early you may draw on the back of your paper.

4. Geometric Transformations

5. Notes Translation (slide) – a SLIDE takes place when a shape moves in one direction from one place to another

6. Notes Reflection (flip) – A FLIP takes place when a shape is flipped across a line and faces the opposite direction. Because the shape ends up facing the opposite direction, it appears to be reflected, as in a mirror. Arrow 1Reflection

7. Notes Rotation (turn) – A TURN takes place when the shape moves like the hands on a clock; most often turns take place in groups of 90º (90º, 180º, 270º, 360º) 90°180° 270°360°

8. Transformations Song (to the tune of “Country Grammar” by Nelly) I’m going right, left baby That’s called a translation Flip, flip baby It’s my reflection, yo! Tip it, tip it, turn it, what Rotating it now Like the hands upon a clock Transform it baby, wow!
