What is the definition of an acute angle?

An acute angle is an angle that measures less than 90 degrees.

How is a right angle defined?

A right angle is defined as an angle that measures 90 degrees. It is formed when two lines meet each other perpendicularly, creating a perfectly square corner.

What defines an obtuse angle?

An obtuse angle is defined as an angle that is greater than 90 degrees but less than 180 degrees. In other words, it is an angle that is wider or "more open" than a right angle, which measures exactly 90 degrees. For example, an angle that measures 120 degrees would be considered obtuse because it is greater than 90 degrees but less than 180 degrees.

Explain the concept of a straight angle.

A straight angle is a geometric term that describes an angle measuring exactly 180 degrees. It forms a straight line and consists of two rays that point in opposite directions. In other words, it is a flat angle that does not involve any bending or deviation. A straight angle represents a complete rotation or half of a circle in terms of degrees, making it one of the most easily recognizable and fundamental angles in geometry.

Describe a reflex angle and its characteristics.

A reflex angle is an angle that measures more than 180 degrees but less than 360 degrees. It is found by extending one of the arms of the angle past 180 degrees on the opposite side. Reflex angles are characterized by their size being greater than a straight angle (180 degrees) but less than a full rotation (360 degrees). They are often seen in geometric shapes and are commonly used in trigonometry and geometry.

What is a complete angle?

A complete angle is an angle that measures exactly 360 degrees. It represents a full circle, where the initial side coincides with the terminal side.

Define a supplementary angle.

Supplementary angles are two angles whose measures add up to 180 degrees. In other words, when two angles are supplementary, they form a straight line.

Explain the concept of a complementary angle.

Complementary angles are two angles whose measures add up to 90 degrees. In other words, when two angles are complementary, the sum of their measures equals a right angle. Each angle in a pair of complementary angles is called the complement of the other. For example, if one angle is 30 degrees, its complementary angle would be 60 degrees, as 30 + 60 = 90 degrees.

What is an adjacent angle?

Adjacent angles are two angles that share a common vertex and a common side, but do not overlap. This means that the angles are side by side and do not have any interior points in common.

Describe the concept of vertical angles.

Vertical angles are a pair of non-adjacent angles formed by the intersection of two lines. They are always congruent, meaning they have the same measurement. Vertical angles are opposite each other and share a common vertex, creating a V-shaped figure. These angles are important in geometry as they help in solving for unknown angles and understanding the relationships between different angles formed by intersecting lines.
