Angle Relations Flashcard

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

How do you solve for x in an angle equation?

Back

To solve for x in an angle equation, isolate x on one side of the equation using algebraic operations.

Front

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

Back

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

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

How do you identify corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the relationship between angle pairs formed by parallel lines and a transversal?

Back

When two parallel lines are cut by a transversal, several angle relationships are formed, including corresponding angles, alternate interior angles, and same-side interior angles.

Front

What is the measure of each angle in an equilateral triangle?

Back

In an equilateral triangle, each angle measures 60 degrees.

Front

How do you find the measure of an unknown angle when given one angle in a linear pair?

Back

To find the measure of an unknown angle in a linear pair, subtract the known angle from 180 degrees.

Front

What is the definition of adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.
