What is an isosceles trapezoid?

Back

An isosceles trapezoid is a quadrilateral with one pair of parallel sides and the non-parallel sides being equal in length.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are always the same distance apart and never meet, regardless of how far they are extended.
