What is an angle in geometry?

Back

An angle is formed by two rays (sides of the angle) that share a common endpoint (the vertex).

Front

How do you name an angle using its vertex and points on its sides?

Back

Front

If m∠1 = 30°, what is m∠3 if they are equal angles?

Back

m∠3 = 30° because equal angles have the same measure.

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that has no thickness and extends infinitely in both directions.

Front

How can a line be named?

Back

A line can be named using any two points on the line, such as Line BC.

Front

What is the definition of a vertex in geometry?

Back

A vertex is a point where two or more lines or edges meet.

Front

What does it mean for angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90°.
