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 other words, acute angles are smaller than right angles (90 degrees), while obtuse angles are larger than right angles.

How can you identify a right angle?

A right angle can be identified by looking at the corner formed by two perpendicular lines. In a right angle, the two lines meet at a corner where they form a 90-degree angle, which is a perfect L-shape.

What is the measure of a straight angle?

A straight angle measures 180 degrees.

How can you identify a reflex angle?

A reflex angle can be identified by its measure being greater than 180 degrees but less than 360 degrees. In geometric terms, a reflex angle forms between the initial side and terminal side on a coordinate plane, where the terminal side extends beyond 180 degrees but not a full rotation of 360 degrees. It appears as an open angle that is larger than a straight angle (180 degrees) but less than a full rotation.

What is the sum of the interior angles of a triangle?

The sum of the interior angles of a triangle is always 180 degrees.

How can you determine if two angles are adjacent?

Two angles are adjacent if they share a common vertex and a common side between them. Visually, this means that they must be next to each other with their sides touching at a single point. In other words, to determine if two angles are adjacent, you need to check if they have the same vertex and share a side.

How can you identify a vertical angle?

A vertical angle is formed when two lines intersect. To identify a vertical angle, look for two angles that share a common vertex and have their sides forming opposite rays. These angles will be congruent, meaning they have the same measure, and are located across from each other when two lines intersect.

What is the measure of a complementary angle?

A complementary angle is an angle that when added to another angle, results in a sum of 90 degrees. Therefore, the measure of a complementary angle is 90 degrees minus the measure of the angle it complements.

How can you identify a supplementary angle?

Supplementary angles are two angles whose measures sum up to 180 degrees. To identify a supplementary angle, you can add the measures of the two angles together. If the sum is equal to 180 degrees, then the angles are supplementary.

What is the difference between a corresponding angle and an alternate angle?

Corresponding angles are located on the same side of the transversal line and in the same relative position when two parallel lines are intersected by a transversal line, whereas alternate angles are located on opposite sides of the transversal line and in the alternate positions when two parallel lines are intersected by a transversal line.
