lines rays and angles

Front

What is a line in geometry?

Back

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

Front

Define 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 line segment?

Back

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

Front

What is a point in geometry?

Back

A point is a precise location or position in a two-dimensional space, represented by a dot.

Front

How do you identify a line segment in a diagram?

Back

A line segment is identified by two endpoints connected by a straight path.

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 defined endpoints.

Front

What is the notation for a line segment?

Back

A line segment is denoted by the endpoints with a bar over them, e.g., segment AB is written as AB̅.

Front

What is the notation for a ray?

Back

A ray is denoted by its starting point and another point on the ray, with an arrow indicating the direction, e.g., ray AB is written as AB→.

Front

What are the types of angles formed by two intersecting lines?

Back

The types of angles formed are vertical angles, adjacent angles, complementary angles, and supplementary angles.

Front

What is the sum of the angles in a triangle?

Back

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