Segment Addition, Midpoint and Distance

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

Define Midpoint.

Back

The midpoint of a segment is the point that divides the segment into two equal parts.

Front

How do you find the midpoint of a segment with endpoints (x1, y1) and (x2, y2)?

Back

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the Distance Formula?

Back

Front

If the endpoints of a segment are A(1, 2) and B(4, 6), what is the distance between A and B?

Back

Front

What does it mean for T to be the midpoint of segment SU?

Back

If T is the midpoint of segment SU, then ST = TU.

Front

If the coordinates of R are (0, 4) and N are (-2, -3), what is the distance RN?

Back

Front

What is the formula to find the length of a line segment given its endpoints?

Back

Front

If AB = 8 and BC = 3, what is AC?

Back

By the Segment Addition Postulate, AC = AB + BC = 8 + 3 = 11.

Front

What is the significance of the distance between two points in geometry?

Back

The distance between two points represents the length of the shortest path connecting them.
