G.CO.2 Experiment with transformations in the plane
Click on the blue translations box to begin experimenting with translations about the coordinate plane.
1) Move point E to (4,2)
and point D to (10,4), to create a vector. How does △ABC transform to △A′B′C′ as a result of this vector?
2) What do you notice about the angle measures of `△ABC` and `△A'B'C'`?
Click on the blue translations box to begin experimenting with translations about the coordinate plane.
3) How does `△ABC` transform to `△A'B'C'` given a vector?
4) What is true about the angle measures of `△ABC` and `△A'B'C'` after a translation occurs?
Click on the green reflections box to begin experimenting with reflections on the coordinate plane.
Move points D and E around the coordinate plane to see how `△ABC` is reflected about line DE.
5) What do you notice about the angle measures of `△ABC` and `△A'B'C'`?
Click on the orange rotations box to begin experimenting with rotations on the coordinate plane.
Move point E around the coordinate plane and use the rotation slider to change the angle of rotation to see how `△ABC` is rotated about point E
6) What do you notice about the angle measures of `△ABC` and `△A'B'C'`?
