Constructing a Perpendicular line

In this activity you will create a perpendicular to the given line segment AB. To ensure that it truly is perpendicular measure the angle created at the intersection and make sure it stays 90 degrees no matter how you move points A/B. Again if you get stuck you can reference the steps by selecting the box. Written out steps: Step 1) Construct a circle centered at A with radius AB. Step 2) Find the intersection of the circle centered at A with line AB, call it point C. Step 3) Create 2 circles centered at C and B both with radius BC Step 4) Find the intersections of the two circles centered at C and B. Call the intersections E,D Step 5) Construct segment EA or DA. this segment will be a perpendicular bisector of CB
