What is an acute angle?

An acute angle is an angle that measures between 0 degrees and 90 degrees. It is smaller than a right angle (90 degrees) and is typically seen in shapes such as triangles and polygons.

What is a right angle?

A right angle is a geometric term that refers to an angle that measures exactly 90 degrees, forming a perfect L-shape with its two arms perpendicular to each other.

What is an obtuse angle?

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. It is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees).

What is a straight angle?

A straight angle is an angle that measures 180 degrees, forming a straight line. It effectively looks like a straight line because it forms a perfectly straight angle without any deviation or bend.

What is a reflex angle?

A reflex angle is an angle that is greater than 180 degrees but less than 360 degrees. It is formed when the vertex of the angle lies on the inside of the angle and the arms of the angle extend beyond forming a full rotation.

What is a complementary angle?

A complementary angle is a pair of angles whose sum is 90 degrees. In other words, when two angles are complementary, they combine to form a right angle.

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.

What is a vertical angle?

A vertical angle is formed when two lines intersect. The angles that are opposite each other at the point of intersection are called vertical angles. Vertical angles have the same measure and are congruent to each other, making them equal in degrees.

What is an interior angle?

An interior angle is an angle formed on the inside of a polygon where two adjacent sides meet. It is the angle between two sides of a polygon that are next to each other.

What is an exterior angle?

An exterior angle is an angle formed between one side of a polygon and the extension of an adjacent side. It is located outside the polygon, opposite to the interior angles. In a polygon, the sum of an exterior angle and its corresponding interior angle is always 180 degrees.
