Let's find the solution for the following rotation:
• Rotation 90 degrees counterclockwise about the origin
Let's find the vertices of the triangle:
Z = (-4, 0)
J = (-5, 2)
L = (0 , -3)
Now, let's find the new vertices after the rotation:
Z' = (0 , 4)
J' = (2, 5)
L' = (-3, 0)
Now we can draw the new triangle, this way:
