(-1, -4) rotated 90 degrees anticlockwise
Rotating a triangle 90 degrees counterclockwise would involve taking an upright triangle and laying is toward the left on its back. Changing position through rotation can cause a better visualization for some problem solving.
90 degreesThere are 90 degrees in a right angle.There are 90 degrees in a right angle
It is an anticlockwise rotation through 90 degrees.
(x,y)-> (-y,x)
Clockwise means turning to your right, counterclockwise is to the left.
180 degrees.

The answer will depend on whether the rotation is clockwise or counterclockwise.
Rotating a triangle 90 degrees counterclockwise would involve taking an upright triangle and laying is toward the left on its back. Changing position through rotation can cause a better visualization for some problem solving.
Something that is tilted 90 degrees has been rotated a quarter turn clockwise or counterclockwise from its original orientation. This means it is now perpendicular to its original position.
The answer will depend on whether the rotation is clockwise or counterclockwise.
A) Rotate 360 degrees counterclockwise, then shift 1 unit up. B) Rotate 180 degrees counterclockwise, then shift 1 unit down. C)Rotate 90 degrees counterclockwise, then shift 1 unit up. D) Rotate 270 degrees counterclockwise, then shift 1 unit down.
They intersect at 90 degrees
1/4 of 360 degrees = 90 degrees which is a right angle
