Answer
L' (5, -1)
M' (8, -3)
N' (1, -8)
The sketch of this rotated triangle is presented below
Step-by-step explanation
Rotating a given coordinate A(x, y) 90° about the origin in the clockwise direction gives a new coordinate A'(y, -x)
So, for each of these,
L (1, 5) → L' (5, -1)
M (3, 8) → M' (8, -3)
N (8, 1) → N' (1, -8)
So, to draw this image, we will mark this new rotated points on the graph, then connect the points to form triangle L'M'N'.
