What is the definition of an angle?

An angle is a figure formed by two rays, called the sides of the angle, that have a common endpoint, known as the vertex of the angle. It is typically measured in degrees and provides a way to quantify the amount of rotation or deviation between the two rays.

How are angles measured?

Angles are typically measured in degrees, with a full circle comprising 360 degrees. Angles can also be measured in radians, with one radian representing the angle formed when the arc length of a circle is equal to its radius. Angles are often identified by their vertex and two rays, known as the arms of the angle, that form the angle.

What is a right angle?

A right angle is an angle that measures exactly 90 degrees, forming a perfect square corner where two lines intersect and are perpendicular to each other.

What is an acute angle?

An acute angle is an angle that measures greater than 0 degrees and 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 means that the angle is greater than a right angle (90 degrees) but not a straight angle (180 degrees).

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. Simply subtract the measures of the two known angles from 180 degrees to calculate the measure of the missing angle.

How do you find the sum of interior angles in a polygon?

To find the sum of the interior angles in a polygon, you can use the formula: (n-2) * 180 degrees, where 'n' represents the number of sides in the polygon. Essentially, you subtract 2 from the number of sides, and then multiply the result by 180 to get the total sum of the interior angles in the polygon.

How do you use a protractor to measure an angle?

To measure an angle using a protractor, place the midpoint of the protractor on the vertex of the angle. Then, align the baseline of the protractor with one side of the angle. Next, read the measurement where the other side of the angle intersects the protractor's scale. The number you see is the measure of the angle in degrees.

What is the relationship between vertical angles?

Vertical angles are a pair of non-adjacent angles formed by the intersection of two lines. They are congruent, meaning they have the same measure. In other words, the relationship between vertical angles is that they are equal in measure.

How do you determine if two angles are congruent?

Two angles are congruent if they have the same measure. To determine if two angles are congruent, you can compare their angle measures using a protractor or other measuring tool. If the measures of the two angles are equal, then the angles are congruent. Another way to determine congruence is by observing the angles' appearance and position in relation to each other - if they look the same, they are likely congruent.
