Point of rotation ConjectureTo find the center of rotation you have to connect to dots on the shaded and the pre-image and the image. For instance, I connected B on the pre-image and B' on the image (on the striped.) Make a perpendicular bisector to line A (what we just made.) Then we need to connect to more points like D and D'and when they intersect at the perpendicular bisector that is your center of rotation.
Double Reflection in Two Intersecting LinesA double refection is like a refection over a 180 degrees or you do 2 90 degree refection. You take a your shaded object and you rotate it 90 degrees then you take that object and the rotate it 90 degrees.
Double Reflection in two parrelle linesYou basically do the same this as in the two intersecting lines but just over a straight line.
Reflections on other linesWe had to find the line of reflection of the Shaded image to the striped image. Then the striped imaged to the dotted image.
Assn. #4I used a parametric equations (one of two or more equations expressing the location of a point on a curve or surface by determining each coordinate separately.) The table is shown in C) the
