How to rotate a triangle 90 degrees?
Understand the Problem
The question is asking for a method to rotate a triangle by 90 degrees, likely within a geometric context. This could involve specifying the point of rotation and how to adjust the triangle's vertices accordingly.
Answer
(x, y) → (y, -x)
To rotate a triangle 90 degrees clockwise about the origin, apply the transformation (x, y) → (y, -x) to each vertex of the triangle.
Answer for screen readers
To rotate a triangle 90 degrees clockwise about the origin, apply the transformation (x, y) → (y, -x) to each vertex of the triangle.
More Information
Rotating an object 90 degrees clockwise involves swapping the coordinates and changing the sign of the original x-coordinate.
Tips
Be careful not to confuse clockwise and counterclockwise rotations. Also, make sure to double-check the sign changes for accuracy.
