Chapter 1 Here are the rules of the game. You are only allowed to use a straightedge (no measuring) and a compass to construct the following. See if you can win the game. You ve got this!! Note: Visit http://www.mathopenref.com/tocs/constructionstoc.html for additional help. 1) Copy a Segment: Practice YOU TRY 2) Bisect a Segment: Practice YOU TRY

3) Copy an Angle: Practice YOU TRY 4) Bisect an Angle: YOU TRY

5) Perpendiculars: a) Construct a line perpendicular to line l and passing through point P on l. Practice YOU TRY b) Construct a line perpendicular to line k and passing through point P not on k. Practice YOU TRY

(Hint: Think about what it allows you to do without actually measuring distance) 2) What do you think is the purpose of constructing something rather than measuring it out (this is open-ended; I want to know what you think)? 3) Did you find this activity helpful in understanding vocabulary (i.e. bisector, perpendicular, etc.)?
