Final answer:
To rotate a triangle 90 degrees clockwise about a point, you can use translation and rotation formulas.
Step-by-step explanation:
To rotate a triangle 90 degrees clockwise about a point, you can use the following steps:
- Translate the triangle so that the desired center of rotation is at the origin.
- Perform the rotation by substituting the new coordinates into the rotation formula:
x' = x * cos(θ) - y * sin(θ)
y' = x * sin(θ) + y * cos(θ)
Translate the triangle back to its original position.
Applying these steps to the triangle with points (-10,11), (2,3), and (4,-5) about the center (-3,-2), we get the new coordinates (11,10), (3,2), and (5,4).
