For #s 1 - 3, do the following:[br][list=1][*]Use the polygon tool to trace the pre-image and place a point at the origin. [/*][*]Use the rotation tool to rotate the pre-image until the image counter-clockwise so it lines up on the given image. [/*][*]Write down the angle of rotation[/*][*]State a coordinate rule for the rotation. (Making a table of the pre-image and image coordinates will help greatly in finding the pattern for the transformation)[/*][/list]
The angle of rotation about the origin (in degrees) is:
[math]\left(x,y\right)\longrightarrow[/math]
