| You need to use a
protractor and a
ruler
to draw a perpendicular
bisector of a line segment. |
|
|
|
A
perpendicular bisector breaks a line into two congruent
sides.
|
|
How do you use a
ruler to draw a
perpendicular bisector? |
| 1. Place the ruler on the
line. |
|
2. Find the half way point of
the line segment. (7 cm is the half way point of this line) |
| 3. The halfway point is where
the perpendicular bisector intersects the line. |
|
|
|
A
perpendicular bisector forms a 90
degree angle at the midpoint. |
|
How do you use a
protractor to draw a
perpendicular bisector? |
| 1. Place the center point of
the protractor on the middle of the line. |
|
2. Draw a line that run through
the 90 degree angle. |
