Trapezoid YOLK with vertices Y(4,0), O(-2,4), L(-2,-1), and K(4,-3) transforms to the vertices of Y'(-4,0), O'(2,4), L'(2,-1), and K'(-4,-3).... What transformation has occurred? What is the function rule?

• Rotation 180 degrees... (x,y) --> (-x,-y)

• Rotation 90 degrees clockwise... (x,y) --> (-y,x)

What is a reflection?

• When you turn an object around a point.
• When you slide an object form one place to another.
• When you flip or mirror an object across a line.
• When you resize an object.
