What is an angle?

An angle is a geometric figure formed by two rays that have a common endpoint, called the vertex of the angle. The two rays are known as the sides of the angle. Angles are measured in degrees and can range from 0 degrees (a zero angle) to 360 degrees (a full rotation).

How do you measure an angle?

To measure an angle, use a protractor by aligning the origin point of the angle with the center of the protractor. Then, read the degree measurement where the second side of the angle intersects the protractor. The angle measurement is typically given in degrees.

What is the difference between acute, right, obtuse, and straight angles?

An acute angle measures less than 90 degrees, a right angle measures 90 degrees, an obtuse angle measures more than 90 degrees but less than 180 degrees, and a straight angle measures 180 degrees.

How can you identify vertical angles?

Vertical angles are identified by two pairs of angles that are across from each other when two lines intersect. These angles have equal measures and are formed by opposite rays. To identify them, simply look for angles that are on opposite sides of the intersection point and have their sides extending in opposite directions.

How do you use a protractor to measure angles?

To use a protractor to measure angles, align the base line of the protractor with one side of the angle. Then, make sure the center point of the protractor is at the vertex of the angle. Finally, read the degree measurement where the other side of the angle intersects with the numbers on the protractor. This will give you the measurement of the angle in degrees.

What is the sum of interior angles in a triangle?

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

How do you find the exterior angle of a triangle?

To find the exterior angle of a triangle, you need to add the two interior angles that are not adjacent to the exterior angle. The sum of the interior angles of a triangle is always 180 degrees, so subtracting this sum from 180 degrees will give you the measure of the exterior angle.

What is a complementary angle?

A complementary angle is a pair of 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.

What is a supplementary angle?

A supplementary angle is a pair of angles that add up to 180 degrees when placed adjacent to each other. These angles can be either adjacent (sharing a common side and vertex) or non-adjacent. When two angles are supplementary, they form a straight line.

How do you find the missing angle in a figure using angle relationships?

To find the missing angle in a figure using angle relationships, you can utilize the properties of the specific figure, such as triangles, quadrilaterals, or other polygons. By knowing the sum of angles in these figures (180 degrees for a triangle, 360 degrees for a quadrilateral), and utilizing properties like supplementary angles (adding up to 180 degrees) or complementary angles (adding up to 90 degrees), you can set up equations and solve for the missing angle by applying the relevant angle relationships within the figure.
