Geometry

Parallel-describes lines in the same plane that never cross or intersect.
-they are marked using arrows.





Perpendicular-describes lines that intersect at right angles (90 degrees).
-they are marked using a small square.

Measure the distance from:

A to B = 8.9 cm

B to C = 8.9 cm

E to F = 8.9 cm

F to G = 8.9 cm

I to J = 8.9 cm

J to K = 8.9 cm

What do you notice about parallel lines?

Always are the same distance apart no matter where you measure as long as you measure using parallel lines.

Identify any parallel line segments

AE // BF

BF // CG

EI // FJ

FJ // GK

AI // CK

Identify any perpendicular line segment

AE to DF

BF to EG

CG to FH

IE to DF

HOMEWORK!!

1. Are line segments AC and DF parallel?

2. Are line segments DF and BE perpendicular?

3. Are line segments AC and BE perpendicular? How do you know?

4. Would a line segment joining A to D be parallel to a line segment BE? How do you know?
