### Scribepost for March 23, 2009

The first thing we did today was number of the day, as usual.
The number was 8756.934, in case you weren't there today, or you
didn't write it down.

After number of the day, we did notes.

Bisect - Bi means "two".
Sect means "cut".
So bisect means to cut in two.
Perpendicular Bisector - A line that divides a line segment in half and is at right angles to it.
eg.

How can you create or draw a perpendicular bisector?
1. Free hand O.K. but not perfect.
2. Protractor gets us 90° angle.
Ruler cuts line in half.

3. Use a compass and create arcs.

a) Open compass to greater than half the distance of line.
b) Place compass of pt. (point) A draw an arc.
c) Place compass on pt. B draw an arc.
d) Use a ruler to connect the intersections of the arcs that line is a perpendicular bisector.

Angles -
angle - the figure formed by two lines with a common end point called a vertex.

acute angle - less than 90°

obtuse angle - more than 90°
less than 180°

angle bisector - the line that divides an angle into two equal parts.

How do we make an angle bisector?
1. Free hand not perfect not accurate enough.
2. Protractor.

3. Compass.

a) Arc from vertex,
b) Arc from pt. S (intersection of line and arc)
c) Arc from pt. T (intersection of line and arc)
d) Line from arc intersection to vertex.

After we did those notes, we worked on some Math Links.
Pg. 116 - 121.

Thank you for reading my scribe, and please comment after, if I made any mistakes, or errors.
I choose JORDAN for the next scribe.

P.S : Sorry my scribe was a little late, my computer kept shutting down.
