What is an angle?

An angle is a figure formed by two rays, called the sides of the angle, that share a common endpoint, known as the vertex of the angle. The measure of an angle is typically given in degrees and indicates the amount of rotation needed to superimpose one ray onto the other.

How is an angle measured?

An angle is measured in degrees, with one full rotation around a point equaling 360 degrees. Angles are typically measured using a protractor, a tool with a half-circle shape and markings that indicate the degree of the angle. To measure an angle, the vertex of the angle is aligned with the center of the protractor, and the line representing one side of the angle is matched up with the baseline of the protractor. The degree reading where the other side of the angle intersects the protractor indicates the measurement of the angle.

What is a right angle?

A right angle is an angle that measures exactly 90 degrees, forming a perfect square corner where two lines intersect, creating perpendicular lines.

What is an acute angle?

An acute angle is an angle that measures less than 90 degrees. It is sharp and narrow, falling between 0 and 90 degrees on a standard Cartesian coordinate system.

What is an obtuse angle?

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. This type of angle is wider and more open than a right angle (90 degrees) but not as wide as a straight angle (180 degrees).

What is a straight angle?

A straight angle is an angle that measures exactly 180 degrees, forming a straight line. It is also known as a line angle.

What is a reflex angle?

A reflex angle is an angle that measures more than 180 degrees but less than 360 degrees. It is formed when the terminal side of an angle rotates more than halfway around a circle.

How do you classify angles based on their measures?

Angles can be classified based on their measures into four categories: acute angles, which measure less than 90 degrees; right angles, which measure exactly 90 degrees; obtuse angles, which measure between 90 and 180 degrees; and straight angles, which measure exactly 180 degrees. Angle classification is important in geometry and helps us understand the relationships between angles in different geometric shapes and figures.

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 their measures add up to a right angle, which is 90 degrees.

What is a supplementary angle?

A supplementary angle is a pair of angles that add up to 180 degrees. In other words, when two angles are adjacent and form a straight line, they are considered supplementary angles.
