1), and Z(1,5) counterclockwise about the point P(-1,1).Please help!!......
Draw the Rotation image of each figure 90 degrees in the given direction about the center point and label the vertices. Triangle XYZ with the vertices X(0,-1), Y (3,1), and Z(1,5) counterclockwise about the point P(-1,1).

Please help!!! I was just taught to do the point of origin!

Just draw a vector from point X to point P, then draw vector at 90 degree angle of the same length. This is where point X' will be located. Repeat with points Y and Z to find Y' and Z'

Draw the triangle on a piece of scratch paper and cut it out. Then, line the triangle up with the points. Then, rotate the triangle 90 degrees counterclockwise.

Hint:
Get a piece fo tissue paper trace the coordinate axis on them, place the origin on your point of rotation, and the rotate all points 90 degrees.
