Angle-Arc Puzzles Created by Students and Mr. Hansen
1. |
Chris M.’s award-winning
puzzle for 2004, edited by Mr. Hansen |
|
Note: The angles are straightforward, but finding the radius (EB or EC) is a bit challenging. Hint: EBJC is a kite. After you find EB (which equals EC), you should find that EJ, EH, and EK are not hard to compute.
