Step 1 - Choose where you want your point of rotation to be by clicking the circle at the origin and moving it around. Click and move the X to rotate triangle ABC. A) Describe what changes as you move the reflection line around. Describe what stays the same. Step 2 - Reflect triangle ABC to a new location on the coordinate plane and write down the original coordinates and the new coordinates (triangle A'B'C'). Be sure to use the correct format for coordinate pairs (x,y). B) How could you be precise with your description of the transformation (how the shape moved from its original position to its new position)?
