Number 9: 1. Use the sketchpad to construct segment AB and locate apoint C on it.2. Construct an arbitrary segment CD3. Using Angle Bisector under CONSTRUCT, construct thebisectors of angle DCB and angle ACD, and locate points E and F on them.4. Display measurement of angle FCD, and angle DCE, andtheir sum on the screen. Drag point D and observe the effect. Does this reveal
what may be a theorem? Yes, it does. Thisconstruction shows that segment CF is perpendicular to segment CE due to the
Theorem 4 from section 2.5.
