Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What is a linear pair of angles?

Back

A pair of adjacent angles whose non-common sides form a straight line. The sum of their measures is 180 degrees.

Front

What does it mean for lines to be parallel?

Back

Lines that never intersect and are always the same distance apart. They have the same slope.

Front

What does it mean for lines to be perpendicular?

Back

Lines that intersect at a right angle (90 degrees).

Front

What is an obtuse angle?

Back

An angle that measures more than 90 degrees but less than 180 degrees.

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 the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What is the relationship between alternate interior angles?

Back

When two parallel lines are cut by a transversal, alternate interior angles are equal.

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).
