Exploring Line Segments and Segment Addition

The video tutorial covers the basics of line and segment notation, explaining how to properly name lines and segments using points. It introduces the concept of betweenness, emphasizing the importance of collinear points. The segment addition postulate is discussed, illustrating how the sum of two smaller segments equals the larger segment when a point is between two others. Finally, the tutorial explains congruent segments, highlighting the difference between length and shape notation.

What is the correct notation for naming a line using two points S and T?

• Line ST

• Segment ST

• S-T

• ST

How do you denote the length of a segment between points S and T?

• Line ST

• Segment ST

• S-T

• ST

What is the length of the segment ST if the coordinates are 8.4 and 3.2?

• 6.2

• 4.2

• 7.2

• 5.2

What is required for betweenness to occur?

• Two points on a line

• Three or more non-collinear points

• Two non-collinear points

• Three or more collinear points

If B is between A and C, which equation must be true?

• AB + BC = AC

• AB + AC = BC

• AC = AB - BC

• AB = BC

Given a segment FH of length 36, and FG of length 21, what is the length of GH?

• 57

• 21

• 15

• 36

What does it mean for two segments to be congruent?

• They have the same length

• They are parallel

• They are perpendicular

• They intersect at a point

Which notation is used to indicate that two segments are congruent?

• Perpendicular lines

• Congruency sign

• Parallel lines

• Equal sign

How do you denote the shape of a segment in notation?

• With a double line above

• With a line above

• With no lines above

• With a dashed line above

What is the difference between talking about the length and the shape of a segment?

• Length uses no lines above, shape uses a line above

• Length uses a line above, shape uses no lines above

• Length uses a double line above, shape uses a single line above

• Length uses a dashed line above, shape uses a solid line above
