4.10 - Geometric Lines

Front

What is a geometric line?

Back

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

Front

What is a vertex in geometry?

Back

A vertex is a point where two or more lines meet. It is often represented by a letter, such as X, Y, or W.

Front

What does it mean for lines to be perpendicular?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

Can you name a type of geometric line that is not straight?

Back

A curved line is a type of geometric line that bends and does not have a constant direction.

Front

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

Back

A line segment has two endpoints, while a ray has one endpoint and extends infinitely in one direction.

Front

What is a parallel line?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

How can you identify a vertex in a shape?

Back

You can identify a vertex by looking for the corners or points where the sides of the shape meet.

Front

What is the symbol for a line in geometry?

Back

The symbol for a line is usually represented by two points on the line with a line above them, like AB.

Front

What is an angle?

Back

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

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.
