What is an angle pair?

An angle pair refers to two angles that share a common side and a common vertex. Angle pairs can be classified based on their relationship, such as complementary angles, supplementary angles, vertical angles, adjacent angles, or linear pair angles, depending on how they interact with one another in terms of their measurement and position.

Define adjacent angles.

Adjacent angles are two angles that share a common vertex and a common side, but do not overlap. They are positioned next to each other and do not have any space between them.

Explain vertical angles.

Vertical angles are pairs of angles that are opposite each other when two lines intersect. They have the same vertex and are congruent, meaning they have equal measures. Vertical angles are always congruent, regardless of the orientation of the intersecting lines, forming a unique and important relationship in geometry.

Describe complementary angles.

Complementary angles are a pair of angles whose measures sum up to 90 degrees. In other words, when two angles are complementary, one angle is the complement of the other, and together they form a right angle. This means that if one angle measures x degrees, then the other angle measures 90 - x degrees to make their total sum 90 degrees.

What are supplementary angles?

Supplementary angles are a pair of angles that add up to 180 degrees when placed adjacent to each other. In other words, when two angles are supplementary, the sum of their measures is 180 degrees.

How are linear pair angles defined?

Linear pair angles are defined as two adjacent angles that form a straight line, adding up to 180 degrees. This means that the two angles are adjacent (share a common side) and the non-common sides form a straight line, creating a pair of supplementary angles.

Define corresponding angles.

Corresponding angles are pairs of angles that lie on the same side of a transversal line intersecting two parallel lines. These angles are equal in measure and are located in the same relative position at each intersection of the transversal with the parallel lines.

Explain alternate interior angles.

Alternate interior angles are a pair of non-adjacent angles that are located on opposite sides of a transversal line and inside a pair of parallel lines. These angles are congruent, which means they have equal measures. In a parallel line setting, alternate interior angles are always equal and can help in proving geometric relationships and theorems related to parallel lines and transversals.

Describe alternate exterior angles.

Alternate exterior angles are a pair of angles that lie on opposite sides of a transversal line and outside a set of intersecting lines. These angles are congruent and have equal measures when the two lines intersect. Alternate exterior angles are formed when a transversal intersects two parallel lines, creating a "Z" shape.

How are corresponding angles related to each other when there are parallel lines cut by a transversal?

Corresponding angles are related to each other when there are parallel lines cut by a transversal because they are congruent. This means that the angles are equal in measure and are in the same position relative to the parallel lines and the transversal. Essentially, corresponding angles lie in the same positions on the same side, either both on the interior or both on the exterior of the parallel lines and the transversal.
