rotation about the origin of 180 degrees counterclockwise

rotation about the origin of 90 degrees counterclockwise
rotation about the origin of 90 degrees counterclockwise

rotation about the origin of 270 degrees counterclockwise
rotation about the origin of 270 degrees counterclockwise

Answer 1

rotation about the origin of 270 degrees counterclockwise

Answer 2

Given a point (−7, 4) on a geometric figure, what is the new point after rotating the figure 90 degrees counterclockwise?

Answer 3

To rotate a point counterclockwise by 90 degrees, we can use the following formula for a 2D rotation:

x' = -y
y' = x

Using this formula, we can find the new coordinates:

x' = -4
y' = -(-7) = 7

Therefore, the new point after rotating the figure 90 degrees counterclockwise is (–4, 7).
