1.2 Segment Addition Postulate

Front

What is the Segment Addition Postulate?

Back

If point B is between points A and C, then AB + BC = AC.

Front

How do you find the distance between two points on a number line?

Back

Subtract the smaller number from the larger number.

Front

If A is at -3 and C is at -7, what is the distance between A and C?

Back

4 units.

Front

Given points A, B, and C on a line, if B is between A and C, what is the correct equation?

Back

AB + BC = AC.

Front

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

Back

AC = AB + BC = 5 + 3 = 8 units.

Front

What does it mean for a point to be 'between' two other points?

Back

It means that the point divides the segment into two smaller segments.

Front

If AB = 2x + 1 and BC = 3x - 2, what is the equation for AC?

Back

AC = AB + BC = (2x + 1) + (3x - 2).

Front

What is the length of segment AC if A is at 1 and C is at 5?

Back

AC = 5 - 1 = 4 units.

Front

If B is at 2, A is at 0, and C is at 5, what is AB + BC?

Back

AB + BC = 2 + 3 = 5 units.

Front

What is the formula to find the length of a segment on a number line?

Back

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