What is an angle?

An angle is the geometric figure formed by two rays that share a common endpoint, known as the vertex. Angles are measured in degrees and can vary in size from 0 degrees (a perfectly straight line) to 360 degrees (a full rotation). Angles play a vital role in geometry and trigonometry, helping to describe the relationships between lines, shapes, and points in space.

What is the vertex of an angle?

The vertex of an angle is the common endpoint where the two rays or line segments that form the angle meet. It is the point where the angle opens up or starts from.

What is the measure of a right angle?

A right angle measures 90 degrees.

How do you classify an angle as acute?

An angle is classified as acute if it measures between 0 degrees and 90 degrees. In other words, an acute angle is any angle that is less than a right angle (90 degrees) but more than a straight angle (180 degrees).

How do you classify an angle as obtuse?

An angle is classified as obtuse if it measures more than 90 degrees but less than 180 degrees. This means that the angle is wider or "more open" than a right angle (which measures exactly 90 degrees) but not as wide as a straight angle (which measures exactly 180 degrees).

What is a straight angle?

A straight angle is an angle that measures exactly 180 degrees. It is a perfectly straight line and is commonly found in geometric shapes such as a straight line or a straight edge of a polygon.

How do you measure an angle using a protractor?

To measure an angle using a protractor, place the center of the protractor on the vertex of the angle. Line up one of the arms of the angle with the 0-degree mark on the protractor. Then, read the number where the other arm of the angle intersects the protractor scale to determine the measure of the angle in degrees.

What is the difference between a line segment and a ray?

A line segment is a part of a line that has two defined endpoints, while a ray is a part of a line that extends infinitely in one direction from a specified point, known as the endpoint. In other words, a line segment has a specific length and is bound by two endpoints, whereas a ray has one endpoint and extends infinitely in one direction.

How do you find the sum of the angles in a triangle?

To find the sum of the angles in a triangle, you simply add the three angles together. The sum of the interior angles of a triangle always equals 180 degrees.

What is the relationship between alternate interior angles?

Alternate interior angles are angles that lie on opposite sides of a transversal line and inside a pair of parallel lines. These angles are congruent, meaning they have the same measure. In other words, if you have two parallel lines intersected by a transversal line, the alternate interior angles will always be equal in measure.
