Chapter 3 review. Numbers 8-10

8. Q: Copy these line segments. Draw the

perpendicular bisectors using two different

methods. Measure the two parts of each

bisected line segment. Record each set of

measurements

A: For line segment "a)" I used the compass method, my bisector was at 3.6cm, my total length was around 7cm

For line segment "b)" I used the paper folding method, my total length was 8cm and the bisector was at 4cm

10. Q: You draw a perpendicular bisector of

a 30-cm line segment. You then draw

a perpendicular bisector of one of the

bisected line segments

A:

a) the shortest length was 7.5cm

b) the shortest line segment compares to the original line as 1/4 of the entire length.
