Geometry Segment Addition

Front

What is Segment Addition Postulate?

Back

The Segment Addition Postulate states that if point B is between points A and C, then AB + BC = AC.

Front

If AB = 5 and BC = 7, what is AC?

Back

AC = AB + BC = 5 + 7 = 12.

Front

What does it mean for segments to be congruent?

Back

Segments are congruent if they have the same length.

Front

If AC = 10 and AB = 4, what is BC?

Back

BC = AC - AB = 10 - 4 = 6.

Front

How do you determine if two segments are congruent?

Back

You compare their lengths; if they are equal, the segments are congruent.

Front

What is the formula to find the length of a segment?

Back

Length of a segment = |x2 - x1|, where x1 and x2 are the endpoints.

Front

If AB = 3 and BC = 4, what is AC?

Back

AC = AB + BC = 3 + 4 = 7.

Front

What is the relationship between the lengths of segments in a straight line?

Back

The lengths of segments on a straight line can be added together to find the total length.

Front

If AB = 8 and AC = 15, what is BC?

Back

BC = AC - AB = 15 - 8 = 7.

Front

What does it mean if two segments are not congruent?

Back

It means that the segments have different lengths.
