What is the definition of an angle?

An angle is a geometric figure formed by two rays that have a common endpoint, called the vertex. The amount of rotation needed to superimpose one ray onto the other is called the angle's measure, typically expressed in degrees or radians. Angles are used to measure the separation or inclination of two lines or planes, and they are fundamental in various mathematical and scientific applications.

What is the difference between an acute angle and an obtuse angle?

An acute angle is an angle that measures less than 90 degrees, while an obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. In simple terms, an acute angle is smaller than a right angle (90 degrees), while an obtuse angle is larger than a right angle.

What is a right angle?

A right angle is an angle that measures exactly 90 degrees, forming a perfect L-shape. It is formed when two lines or line segments meet each other at a point and create equal perpendicular angles on each side.

Can two acute angles add up to make a right angle?

No, two acute angles cannot add up to make a right angle. A right angle measures exactly 90 degrees, while acute angles are less than 90 degrees. So the sum of two acute angles will always be less than 90 degrees, and therefore cannot equal a right angle.

What is a straight angle?

A straight angle is an angle that measures exactly 180 degrees. It forms a straight line, with the two rays of the angle extending in opposite directions. It is the largest possible angle in standard Euclidean geometry.

Can a straight angle be divided into two right angles?

No, a straight angle cannot be divided into two right angles because a straight angle measures 180 degrees, which is already equivalent to two right angles. In other words, a straight angle is made up of two right angles combined together.

What is a complementary angle?

A complementary angle is the angle that when added to another angle results in a sum of 90 degrees. In other words, two angles are complementary if the sum of their measures equals 90 degrees.

Can two complementary angles be obtuse?

No, two complementary angles cannot both be obtuse as each complementary angle must have a measure between 0 and 90 degrees. Obtuse angles have measures greater than 90 degrees, so it is not possible for two angles to be both obtuse and complementary to each other.

What is a supplementary angle?

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

Can two supplementary angles be acute?

No, two supplementary angles cannot both be acute because the sum of two acute angles is always less than 180 degrees. Supplementary angles are a pair of angles that add up to 180 degrees, so at least one of the angles must be obtuse or a right angle in order to total to 180 degrees.
