10. Rotate the figure shown 180° clockwise. Record the coordinates of the 3 points<br> image.
inna [77]

Answer:

J' = (6,7)

K' = (6,2)

L'=(3,7)

Step-by-step explanation:

From the attachment, we have:

J = (-6,-7)

K = (-6,-2)

L = (-3,-7)

Rotation: 180 degrees clockwise

Required

Find J', K' and L'

When a point (x, y)is rotated 180 degree clockwise, the resulting point is: (-x, -y)

So, we have:

J' = (6,7)

K' = (6,2)

L'=(3,7)
