Geometry Chapter 1 Review

Front

What is a line segment?

Back

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

Front

Define collinear points.

Back

Collinear points are points that lie on the same straight line.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter P of a rectangle is given by the formula P = 2(length + width).

Front

If the perimeter of a rectangle is 26 cm and the length is 10 cm, what is the width?

Back

The width is 3 cm.

Front

What does it mean for points to be collinear?

Back

It means that the points can be connected by a single straight line.

Front

What is the relationship between the sides of a rectangle and its perimeter?

Back

The perimeter is the total distance around the rectangle, which depends on both the length and width.

Front

How do you find the length of a side of a rectangle if you know the perimeter and the length of the other side?

Back

Rearrange the perimeter formula: width = (Perimeter/2) - length.

Front

What is the definition of a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

If AC = 48 and AB = 16, what is the length of BC?

Back

BC = AC - AB = 48 - 16 = 32.
