What is the definition of an angle?

An angle is a geometric figure formed by two rays sharing a common endpoint, called the vertex. It is measured in degrees or radians and represents the amount of rotation needed to bring one ray into coincidence with the other. Angles can be classified based on their measure as acute (less than 90 degrees), right (exactly 90 degrees), obtuse (more than 90 degrees but less than 180 degrees), straight (exactly 180 degrees), or reflex (more than 180 degrees but less than 360 degrees).

How do you classify angles based on their measure?

Angles can be classified based on their measure as acute angles (less than 90 degrees), right angles (exactly 90 degrees), obtuse angles (greater than 90 degrees but less than 180 degrees), and straight angles (exactly 180 degrees). Additionally, angles that are greater than 180 degrees but less than 360 degrees are considered reflex angles, while angles that have a measure of exactly 360 degrees are called full angles.

What is a right angle?

A right angle is a geometric term used to describe an angle that measures exactly 90 degrees. This angle is formed when two lines meet each other perpendicularly, creating a perfect L shape with equal sides.

What is an obtuse angle?

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. It is wider than a right angle (90 degrees) and does not form a straight line.

What is an acute angle?

An acute angle is an angle that is less than 90 degrees. It is a sharp angle that is smaller than a right angle.

How do you determine the size of an angle using a protractor?

To determine the size of an angle using a protractor, place the center point of the protractor on the vertex of the angle. Align one of the protractor's arms with one side of the angle. Read the measurement where the other side of the angle intersects the protractor scale. The number you read is the measure of the angle in degrees.

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

To find the sum of the angles in a triangle, simply add the three angle measurements together. In a triangle, the sum of the interior angles is always 180 degrees.

What is a complementary angle?

A complementary angle is an angle that, when added to another angle, results in a sum of 90 degrees. In other words, two angles are considered complementary if they add up to form a right angle.

What is a supplementary angle?

A supplementary angle is a pair of angles that add up to 180 degrees when placed adjacent to each other, sharing a common side and vertex.

How do you use the protractor to measure and draw angles accurately?

To measure and draw angles accurately using a protractor, first place the central point of the protractor at the vertex of the angle you want to measure. Align one of the straight edges of the protractor with one of the two sides of the angle. Read the measurement where the other side of the angle intersects the protractor scale. To draw an angle, place the protractor in the same way as when measuring, mark the measurement on one of the sides of the angle, and then draw the other side to create the desired angle. Make sure to hold the protractor steady and use a sharp pencil for precision.
