Demonstrating the properties of rotations, if a line segment with endpoints (0,−3) and (0,−7) is rotated 90° clockwise, what is an endpoint of this rotated segment?
To rotate the line segment 90° clockwise, we can use the rotation matrix [[0, 1], [-1, 0]].
Let's denote the original coordinates of the endpoints as A(0, -3) and B(0, -7).
To find the endpoint after rotation, we can multiply the rotation matrix by the original coordinates of the endpoint.
For A(0, -3):
[[0, 1], [-1, 0]] * [0, -3] = [-3, 0]
For B(0, -7):
[[0, 1], [-1, 0]] * [0, -7] = [-7, 0]
Therefore, the endpoint of the rotated segment is (-3, 0).
