4.10 - Geometric Lines

Front

What is a vertex in geometry?

Back

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

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

What does it mean for lines to be perpendicular?

Back

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

Front

What is 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

What is a straight line?

Back

A straight line is the shortest distance between two points and has no curves.

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.

Front

What are parallel lines?

Back

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

Front

What is a transversal line?

Back

A transversal line is a line that crosses two or more other lines.
