Drawing Angle Bisectors

Drawing Angle Bisectors : Angle bisectors cuts an angle in half.

Method 1: Use a compass.

1.Sharp point on the vertex.
2.Make an arc that intersects both rays of the angle, lable those instructions
3.From two new intersections make two more arcs.
4.With a ruler draw a line from the arc intersect onto the vertex.
5.That line is your angle bisector.
Here is a video on method 1.

Method 2: use a protractor

1.Measure the angle with a protractor.
2.divide the angle measurement by 2.
3.mark the halfway point using the protractor.
4.use a ruler to connect the halfway point to the vertex.
5. That is your (BEAUTIFUL) angle bisector.

Sorry I can't find a video on method 2.
but...

Here is a link on Angle bisectors.

And some pictures.
THANKS FOR LOOKING. PLEASE COMMENT.
