What is the definition of a median in a triangle?

Back

A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect, even if extended infinitely.

Front

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

Back

When two lines are intersected by a transversal, corresponding angles are congruent if the lines are parallel.

Front

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

Back

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

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

How can you determine if two triangles are congruent?

Back

Two triangles are congruent if their corresponding sides and angles are equal.
