A _________________ is a quadrilateral with exactly one pair of parallel sides. If the legs of
a trapezoid are congruent, the trapezoid is an __________________ trapezoid.
Each nonparallel side is
called a leg.
Each ∥ side is
called a base.
Base angles are two
consecutive angles whose
common side is a base.
Isosceles Trapezoid Theorems
• In an isosceles trapezoid, each pair of base angles is ___________________.
• If a trapezoid has one pair of congruent base angles, then it is ____________.
• A trapezoid is isosceles if and only if it’s ________________ are congruent.
14. In trapezoid EFGH, FH  9. Find AG.
13. Find mJ in trapezoid JKLM.
