Discover the construction used to reflect point, A, over line DE.

1. Using the Circle with Center through Point tool, create a circle with Center at Point A
**Make sure the circle crosses the line of reflection DE twice!!!
2. Using the Intersect tool, create a points where the circle intersects the line of reflection.

**Point at Intersection 1: ______ Point at Intersection 2: ______**3. Find the Radius of Circle A Using the Distance or Length tool measure the distance from the center of the circle to any point on the circle.**Radius of Circle A: _______**4.Using the Circle with Center and Radius tool create two circles: • Create a circle with center at Point at Intersection 1 (from Step 2) and radius (from Step 3)**Center: _______ Radius: ________**• Create a circle with center at Point at Intersection 2 (from Step 2) and radius (from Step 3.)**Center: _______ Radius: ________**5. Using the Intersect tool, create a point where the two new circles intersect.*How could you check if this point is Point A reflected over Line R?***Write steps to construct a reflection of a point over a line on paper using a compass**
