Geometry Chapter 1 Exam

Front

What are the endpoints of a ray?

Back

Endpoints are the two points that define the start and end of a ray.

Front

What is the symbol for congruence?

Back

The symbol for congruence is '≅', indicating that two figures have the same shape and size.

Front

Define a line segment.

Back

A line segment consists of two endpoints and all the points in between.

Front

What is the segment addition postulate?

Back

The segment addition postulate states that if point B is between points A and C, then AB + BC = AC.

Front

What is a point in geometry?

Back

A point is a location in space represented by a dot and has no dimensions.

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

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect.

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.

Front

What is the formula for finding the length of a line segment?

Back

The length of a line segment can be found using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is a ray in geometry?

Back

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