What is the definition of an angle?

An angle is a geometric figure formed by two rays (or lines) that share a common endpoint, known as the vertex.

What is a right angle?

A right angle is an angle that measures exactly 90 degrees, formed by two perpendicular lines intersecting each other. It is a fundamental concept in geometry and is commonly represented by a small square symbol in diagrams.

How do you measure angles?

Angles are measured in degrees using a protractor. To measure an angle, place the protractor with the origin (center point) over the vertex (corner) of the angle, align the baseline of the protractor with one side of the angle, and then read the number where the other side of the angle crosses the protractor scale. This number represents the measure of the angle in degrees.

What is the relationship between complementary angles?

Complementary angles are two angles that add up to 90 degrees. In other words, when you put two complementary angles together, they form a right angle.

What is the relationship between supplementary angles?

Supplementary angles are two angles that add up to 180 degrees. In other words, when you add the measures of two supplementary angles together, the sum is always 180 degrees.

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

An acute angle measures less than 90 degrees, an obtuse angle measures between 90 and 180 degrees, and a straight angle measures exactly 180 degrees.

How do you identify vertical angles?

Vertical angles are the pair of angles formed by two intersecting lines where the angles are opposite each other. To identify vertical angles, look for angles that are across from each other when two lines intersect, always having the same angle measurements as their counterparts.

What is the definition of adjacent angles?

Adjacent angles are two angles that share a common vertex and a common side between them, but do not overlap. In other words, they are angles that are side by side and have a common side and a common vertex at their intersection.

How do you determine the sum of interior angles of a polygon?

To determine the sum of the interior angles of a polygon, you can use the formula: (n-2) * 180, where n represents the number of sides in the polygon. This formula works for all polygons, including triangles, quadrilaterals, pentagons, hexagons, and so on. By plugging in the number of sides into the formula, you can easily calculate the total sum of the interior angles of the polygon.

How do you find the measure of an unknown angle using angle relationships?

To find the measure of an unknown angle using angle relationships, you can use properties such as linear pairs, vertically opposite angles, corresponding angles, alternate interior angles, and alternate exterior angles. By identifying these relationships within a given set of angles, you can set up equations or use geometric rules to find the value of the unknown angle. Additionally, you can use the sum of angles in a triangle (180 degrees), a quadrilateral (360 degrees), or a straight line (180 degrees) to help determine the measure of the unknown angle.
