Angles and Lines

Front

What is a point in geometry?

Back

A point is a precise location or position in space, typically represented by a dot.

Front

What are parallel lines?

Back

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

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 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 a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.

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 right angle?

Back

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

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at one point.

Front

What is a transversal?

Back

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

Front

What is the sum of angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.
