Geometry Basics

Front

What is a POINT in geometry?

Back

A POINT has no dimension; it represents a specific location in space.

Front

What is an ANGLE?

Back

An ANGLE is formed by two rays that meet at a common endpoint called the vertex.

Front

What is a LINE?

Back

A LINE extends infinitely in both directions and has no endpoints.

Front

What is the sum of the measures of complementary angles?

Back

The sum of the measures of complementary angles is 90 degrees.

Front

What is the sum of the measures of supplementary angles?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

What are ADJACENT ANGLES?

Back

Adjacent Angles are angles that are next to each other and share a common side.

Front

What is a RAY in geometry?

Back

A RAY is a part of a line that has one endpoint and extends infinitely in one direction.

Front

What is a VERTEX?

Back

A VERTEX is the point where two rays meet to form an angle.

Front

What is a LINE SEGMENT?

Back

A LINE SEGMENT is a part of a line that has two endpoints.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect; they are equal in measure.
