Trapezoids+P5

By: Elizabeth, Blake and Libby TRAPEZOID VOCABULARY // Trapezoid // - A polygon formed of two non-congruent Parallel sides joined by diagonals. // Diagonal // - A line connecting two non-consecutive vertices. // Bases // - The two Parallel lines. // Legs- // The lines that connect the two bases.
 * //__ Theorems __//**

If the trapezoid is isosceles, then each pair of base angles is congruent.


 * Converse- ** If a pair of base angles are congruent, and then it is an isosceles trapezoid.

Trapezoids are isosceles if and only if their diagonals are congruent.

Midsegment (median)- connects legs to the midpoints.

The midsegment of a trapezoid is parallel to the bases.

The midsegment is half the sum of the bases.
