Angles

Front

What are adjacent angles?

Back

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

Front

What is the definition of supplementary angles?

Back

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

Front

What is the definition of complementary angles?

Back

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

Front

What are vertical angles?

Back

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

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

Front

What is the relationship between complementary and supplementary angles?

Back

Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees.

Front

How can you identify vertical angles in an intersecting line diagram?

Back

Vertical angles are formed by two intersecting lines and are located opposite each other.

Front

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

Back

In an equilateral triangle, each angle measures 60 degrees.

Front

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

Back

Acute angles measure less than 90 degrees, right angles measure exactly 90 degrees, and obtuse angles measure more than 90 degrees but less than 180 degrees.

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that form a straight line, and their measures add up to 180 degrees.
