Reflections Experiment! Name: ________________ Experiment 1: Step 1: Graph ΔABC with points at 𝐴(1,2), 𝐵(−3,4), 𝐶(−2, −5)Step 2: Record your points under “original points” on the chart. Step 3: Reflect the whole triangle across 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?
Experiment 2: Step 1: Graph ΔABC with points at 𝐴(1,2), 𝐵(−3,4), 𝐶(−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.
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: (𝒙, 𝒚) → (
Original Points 𝐴 (1,2) 𝐵 (−3,4) 𝐶 (−2,
−5)Prime Points after
reflection over the y-axis

Rotations Experiment! Name: _______________________
Experiment 1: Step 1: Graph ΔABC with points at
𝐴(1,2), 𝐵(−3,4), 𝐶(−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.
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): (𝒙, 𝒚) → (
Rotate 180°: (𝒙, 𝒚) → (
Rotate 270° Clockwise (Same as 90° Counterclockwise): (𝒙, 𝒚) → (
