4. Constructing Perpendiculars Through a Point

For Tuesday, 9/3/13, our topic is more on construction.

Lesson Objective (LO):  

SWBAT use constructions to explore attributes of perpendicular bisectors.

The two construction models we are doing are the following:  (Do these on the right side of your notebook)

1.  Constructing a perpendicular through a point on a line.

Your job is to draw your own and write, in your own words, the steps needed to make this construction.

(Hint:  the first step is to draw a segment and put a point on it somewhere)

2.  Constructing a perpendicular through a point not on a line

(I haven't been able to find a youtube video of this yet.  I will update this post as soon as I find it.)

Your job is to again draw your own and write, in your own words, the steps needed to make this construction.  (Hint:  the first step is to draw a segment and put a point somewhere above it.)

The final drawing for each of the above two tasks is going to look like this:
