Angle Pairs, Cross-Sections & Unique Polygons

Front

What are vertical angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What are complementary angles?

Back

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

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 a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments.

Front

What is a unique triangle?

Back

A unique triangle is a triangle that can be formed with a specific set of side lengths.

Front

How many sides does a triangle have?

Back

A triangle has three sides.

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 is a cross-section?

Back

A cross-section is the intersection of a solid and a plane.

Front

What is the difference between a regular and irregular polygon?

Back

A regular polygon has all sides and angles equal, while an irregular polygon does not.
