Geometry A 1.2 Linear Measure

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What is the formula to find the length of a line segment between two points (x1, y1) and (x2, y2)?

Back

Length = √((x2 - x1)² + (y2 - y1)²)

Front

If Y is between X and Z, how do you express the relationship of their lengths?

Back

XY + YZ = XZ.

Front

What is the value of c if XY = 11, YZ = 4c, and XZ = 83?

Back

c = (XZ - XY) / 4 = (83 - 11) / 4 = 18.

Front

What is the length of YZ if c = 18?

Back

YZ = 4c = 4 * 18 = 72.

Front

How do you convert inches to centimeters?

Back

1 inch = 2.54 centimeters.
