What is a line segment?

A line segment is a straight path connecting two points, which includes those two points and all the points in between them. It has a specific length and is considered to be infinitely divisible.

How is a line segment different from a line?

A line segment is a part of a line that has two endpoints, while a line extends indefinitely in opposite directions. A line has no endpoints and continues infinitely in both directions, while a line segment is a finite portion of a line with two distinct endpoints.

What are the two endpoints of a line segment?

The two endpoints of a line segment are the distinct points at which the segment starts and ends.

How is the length of a line segment measured?

The length of a line segment is measured by determining the distance between its two endpoints using a ruler, tape measure, or other measuring tools. The measurement is typically expressed in units such as inches, centimeters, or feet depending on the scale being used.

What is the midpoint of a line segment?

The midpoint of a line segment is the point that is exactly halfway between the two endpoints of the line segment. It divides the line segment into two equal parts and is equidistant from the endpoints in terms of length along the line segment. This midpoint is often denoted by the coordinates (x, y) on a coordinate plane or by a specific formula to calculate it.

How is the midpoint of a line segment calculated?

The midpoint of a line segment is calculated by averaging the x-coordinates and y-coordinates of the endpoints of the line segment. To find the midpoint in a Cartesian plane, you add the x-coordinates of the endpoints and divide by 2 to get the x-coordinate of the midpoint, and do the same for the y-coordinates to find the y-coordinate of the midpoint. This gives you the coordinates of the point that lies exactly halfway along the line segment.

What is an angle?

In geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. An angle is typically measured in degrees and is used to describe the amount of turn or separation between the rays.

How do you measure the size of an angle?

An angle is typically measured in degrees. To measure the size of an angle, you can use a protractor. Align the center of the protractor with the vertex of the angle and then read the degree measure where one side of the angle intersects with the protractor scale. The degree measure will indicate the size of the angle, which can range from 0 degrees for a completely closed angle to 180 degrees for a straight angle to 360 degrees for a full rotation.

What are the three types of angles based on their size?

The three types of angles based on their size are acute angles (less than 90 degrees), right angles (exactly 90 degrees), and obtuse angles (more than 90 degrees but less than 180 degrees).

How are angles named or labeled?

Angles are named or labeled using one of three methods: by a single letter, by three points, or by a number. A single letter, such as ?A, is used to represent an angle. Three points, with the middle point being the vertex, are used to name an angle, such as vertex B with points A and C on each side would be written as ?ABC. Angle measurement in degrees can also be used to label angles, such as ?30°.
