Semester Review - Module 1

Front

If R is the midpoint of segment QS, find QS if R is at (17, 0).

Back

QS = 34

Front

Find the other endpoint of the line segment with the given endpoint A(-4, 2) and midpoint M(8, 7).

Back

The other endpoint is (20, 12).

Front

Solve for x in the equation 2x + 5 = 71.

Back

x = 33

Front

What is the midpoint between (3,-1) and (7,-5)?

Back

The midpoint is (5,-3).

Front

Find AB and BC if AB = 11 and BC = 22.

Back

AB = 11 and BC = 22.

Front

Definition: Midpoint.

Back

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

Front

Formula for finding the midpoint between two points (x1, y1) and (x2, y2).

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Front

If the coordinates of point A are (x1, y1) and point B are (x2, y2), how do you find the distance AB?

Back

Distance AB = √((x2 - x1)² + (y2 - y1)²).

Front

What is the distance between points (1, 2) and (4, 6)?

Back

Distance = 5.

Front

If the length of segment AB is 20, what is the length of segment AC if C is the midpoint of AB?

Back

AC = 10.
