Segment Addition Postulate

Front

What is the 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 = 2 and BC = 3, what is AC?

Back

AC = AB + BC = 2 + 3 = 5.

Front

How do you determine if two segments are congruent?

Back

Two segments are congruent if they have the same length.

Front

If AC = 6 and AB = 2, what is BC?

Back

BC = AC - AB = 6 - 2 = 4.

Front

What does it mean for segments to be congruent?

Back

Segments are congruent if they are equal in length.

Front

If AB = 3 and AC = 5, what is BC?

Back

BC = AC - AB = 5 - 3 = 2.

Front

If two segments are not congruent, what can we say about their lengths?

Back

Their lengths are different.

Front

If point D is between points A and C, and AD = 4 and DC = 2, what is AC?

Back

AC = AD + DC = 4 + 2 = 6.

Front

What is the formula for finding the length of a segment?

Back

Length of a segment = Distance between its endpoints.

Front

If AB = 1 and AC = 4, what is BC?

Back

BC = AC - AB = 4 - 1 = 3.
