If line segment DE is 8 cm and FG is 3 times the length of DE, what is the length of FG?

Back

24 cm

Front

What is the measure of Segment TP if the options are 3.5, 7, 14, and 7√2?

7

Front

If EF is 8 cm and FG is 12 cm, what is the length of EG?

Back

20 cm

Front

Define collinear points.

Back

Collinear points are points that lie on the same straight line.

Front

What is the formula for finding the length of a line segment between two points (x1, y1) and (x2, y2)?

Back

Front

What does it mean for line segments to be parallel?

Back

Parallel line segments are line segments that never intersect and are always the same distance apart.

Front

If two line segments are collinear, how do you find the total length of the combined segment?

Back

Add the lengths of the individual segments.

Front

What is the relationship between the lengths of parallel line segments?

Back

Parallel line segments can have different lengths; their lengths are independent of each other.
