Reflections Experiment! Name: ________________ Experiment 1: 427545511430 00 Step 1: Graph ΔABC with points at ?(1,2), ?(?3,4), ?(?2, ?5)Step 2: Record your points under “original points” on the chart. Step 3: Reflect the whole triangle across the y-axis. Original Points ? (1,2)? (?3,4)? (?2, ?5)Prime Points after reflection over the y-axis Step 4: Record the new points under “y-axis” on the chart. What do you notice about what happened to each of the points after reflecting across the y-axis? 4271010160655 00 Experiment 2: Step 1: Graph ΔABC with points at ?(1,2), ?(?3,4), ?(?2, ?5)Step 2: Record your points under “original points” on the chart. Step 3: Reflect your original triangle across the x-axis. Step 4: Record these new points under “x-axis” on the chart.Original Points ? (1,2)? (?3,4)? (?2, ?5)Prime Points after reflection over the x-axis What do you notice about what happened to each of the points after reflecting across the x-axis? In Summary: Write rules for each of your experiments below: Reflect across y-axis: (?, ?) → ( Reflect across x-axis: (?, ?) → (Rotations Experiment! Name: _______________________ Original Points ?(1,2) ?(?3,4) ?(?2, ?5) 90° 180° 270° Experiment 1: Step 1: Graph ΔABC with points at ?(1,2), ?(?3,4), ?(?2, ?5)Step 2: Rotate ΔABC 90° clockwise. Step 3: Record the new points under “90°” on the chart. Step 4: Rotate the original ΔABC 180° clockwise. Step 5: Record the new points under “180°” on the chart. Step 6: Rotate the original ΔABC 270° clockwise. Step 7: Record the new points under “270°” on the chart. -296072375182 What do you notice about what happened to each of the points after rotating 90°? What do you notice about what happened to each of the points after rotating 180°? What do you notice about what happened to each of the points after rotating 270°? In Summary: Write rules for each of your experiments: Rotate 90° Clockwise (Same as 270° Counterclockwise): (?, ?) → ( Rotate 180°: (?, ?) → ( Rotate 270° Clockwise (Same as 90° Counterclockwise): (?, ?) → (
