Question

rotate the points 90 degrees around the origin: A 4,-3 B 4,0 C 8,0

Answer 1

To rotate a point 90 degrees counterclockwise around the origin, you can switch the x and y coordinates and negate the new y coordinate.

For point A (4, -3):
The new x-coordinate: 0 - (-3) = 3
The new y-coordinate: 4

So, the rotated point A is (3, 4).

For point B (4, 0):
The new x-coordinate: 0 - 0 = 0
The new y-coordinate: 4

So, the rotated point B is (0, 4).

For point C (8, 0):
The new x-coordinate: 0 - 0 = 0
The new y-coordinate: 8

So, the rotated point C is (0, 8).
