Answer:
You would need to include in your description, angle of rotation, direction and center of rotation
Explanation:
we know that
When the triangle is rotated,every point on the triangle is turned by an angle about a center of rotation. The center of rotation is the point that a triangle rotates about. If the rotation is in the same direction as the hands of a clock, the direction is clockwise. If the rotation is in the opposite direction as the hands of a clock, the direction is counter-clockwise
so
To describe a rotation, we need to say what angle the triangle has been turned by, the direction and where the center of rotation is.
therefore
You would need to include in your description, angle of rotation, direction and center of rotation
