Example Question #1 : How To Graph An Ordered Pair
The vertices of a triangle are given by . The triangle is rotated about the origin by degrees clockwise. What are the new coordinates?
The coordinates form a triangle in the second quadrant with a side along the y-axis. The rotation about the origin by degrees clockwise results in a triangle in the first quadrant with a side along the x-axis. There are two responses that give triangles along the x-axis:
A rotation and a dialation by a factor of is given by
, so the correct answer is
