Front

What is a line segment?

Back

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

Front

What is a line?

Back

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

Front

What is a point in geometry?

Back

A point is a precise location or position in space that has no dimensions, represented by a dot.

Front

What is an angle?

Back

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

Front

What is a right angle?

Back

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

Front

What is a ray?

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 and a finite length.

Front

What are the types of angles based on their measures?

Back

The types of angles include acute (less than 90 degrees), right (exactly 90 degrees), obtuse (greater than 90 degrees but less than 180 degrees), and straight (exactly 180 degrees).

Front

What is the vertex of an angle?

Back

The vertex of an angle is the point where the two rays meet.

Front

How do you identify an angle in a diagram?

Back

An angle is typically identified by the two rays that form it and the vertex where they meet, often marked with a small arc.
