Reflections Experiment! Name: ________________ Experiment 1: 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. 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?

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) → (

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°?

Original Points 𝐴(1,2) 𝐵(−3,4) 𝐶(−2,

90°

180°

270°

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) → (
