What is the definition of an angle?

An angle is a geometric figure that is formed by two rays that share a common endpoint, called the vertex. The measurement of an angle is typically expressed in degrees, with a full rotation around the vertex equal to 360 degrees. The size of an angle is determined by the amount of rotation needed to superimpose one ray on the other.

How is an angle measured?

An angle is measured in degrees, which is a unit of angular measurement. The starting point for measuring an angle is its initial side, which is typically drawn as a ray extending from a common point called the vertex. The angle is then measured by the amount of rotation needed to bring the terminal side of the angle to its final position.ANGLES can also be measured in radians or grads, depending on the context and application.

What is a straight angle?

A straight angle is an angle that measures exactly 180 degrees, forming a straight line. It is a half-turn angle formed by a pair of opposite rays, and it is often represented by a horizontal line segment.

What is a right angle?

A right angle is a geometric concept in which two lines or line segments meet at a 90-degree angle, forming a perfect L shape. This angle is commonly seen in shapes such as squares, rectangles, and triangles, and is a fundamental angle in geometry and trigonometry.

What is an acute angle?

An acute angle is an angle that measures greater than 0 degrees but less than 90 degrees. It is a sharp angle that is smaller than a right angle (90 degrees) and an obtuse angle (greater than 90 degrees).

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 larger than a right angle (which is exactly 90 degrees) and appears wider or more open.

What is a complementary angle?

A complementary angle is an angle that, when added to another angle, equals 90 degrees. In other words, two angles are complementary if their sum is 90 degrees.

What is a supplementary angle?

A supplementary angle is a pair of angles whose measures add up to 180 degrees. In other words, when two angles are supplementary, they combine to form a straight line.

How do you find the missing angle in a triangle?

To find the missing angle in a triangle, you can use the fact that the sum of all angles in a triangle is always 180 degrees. Subtract the measures of the two known angles from 180 degrees to calculate the missing angle.

How do you determine if two angles are congruent?

Two angles are congruent if they have the same measure. This means that the degree measure of one angle is equivalent to the degree measure of the other angle. To determine if two angles are congruent, you can compare their measurements using a protractor or by using known angle relationships in geometric figures or equations.
