Segment Lengths and Midpoints

This video tutorial covers unit one, lesson two on measuring and constructing segments. It outlines objectives such as measuring line segments, applying the segment addition postulate, defining midpoint and bisectors, and constructing congruent segments. The lesson includes examples and guided practice on these topics, emphasizing the importance of understanding congruence and the segment addition postulate. The tutorial also explains how to find midpoints and use bisectors in problem-solving.

What is the primary objective of the lesson on measuring and constructing segments?

• To explore the properties of triangles

• To measure line segments and apply the segment addition postulate

• To understand the concept of congruent angles

• To learn about angles and their properties

How is the length of a segment between two points A and B represented?

• As the product of A and B

• As the sum of A and B

• As the difference between A and B

• As the length of segment AB or simply AB

What does it mean if two segments are congruent?

• They have different lengths

• They have the same length

• They are parallel

• They are perpendicular

According to the segment addition postulate, if B is between A and C, what is true?

• AB + BC = AC

• AB - BC = AC

• AB * BC = AC

• AB / BC = AC
