Front

What is a polygon?

Back

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

Front

What does it mean to rotate a polygon 180 degrees?

Back

Rotating a polygon 180 degrees means turning it around a point so that each point of the polygon moves to a position directly opposite its original position.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What are skew lines?

Back

Skew lines are lines that do not intersect and are not parallel, existing in different planes.

Front

What does it mean for lines to be parallel?

Back

Lines are parallel if they are in the same plane and do not intersect, regardless of how far they are extended.

Front

What are complementary angles?

Back

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

Front

What is the sum of the angles in a triangle?

Back

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

Front

What is the relationship between opposite rays?

Back

Opposite rays are two rays that share a common endpoint and extend in opposite directions.

Front

How do you determine if two lines are parallel using angles?

Back

Two lines are parallel if the corresponding angles or alternate interior angles formed by a transversal are equal.

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points.
