We start with angle A. Point B is on one of the sides.[br][br]Use the <compass tool> to construct a circle with radius AB and center at A.[br]Use the <intersection tool> to mark the intersection of the circle with the other side of the angle, point C.[br]What can you say about segments AB and AC?[br][br]Use the <compass tool> to construct two more circles, with radius AB, and centers and B and C.[br]These will intersect at A and at a new point. [br]Use the <intersection tool> to mark the second intersection, point D.[br][br]Use the <polygon tool> to construct quadrilateral ABCD. (Notice how the ORDER is important!)[br]How would you classify quadrilateral ABDC? [br]Explain why this is so.[br][br]Use the <ray tool> to construct ray AD. [br]How does ray AD relate to angle BAC? [br](Again, order is important. The middle letter is the vertex of an angle when naming it with 3 letters).[br][br]Use the <segment tool> to construct segment BC.[br]How does ray AD relate to segment BC? [br]What special name do you have for ray AD?[br]Which one is doing the cutting in half (bisector), and which is being cut (bisectED).[br][br]Finally, how are angles BAD and CAD related? Explain why.
