  2. Things to Know About a Trapezoid A trapezoid quadrilateral that has exactly one pair of parallel sides Formula of area is A=1/2*b(h) b1 h b2

  3. Proving a Trapezoid A C E Given: AT || CO AC congruent TO Prove: <A congruent <T <ACO congruent <TOC F O T Statements: AT || CO AC congruent TO TACO is an isosceles trapezoid. AT & CO are bases of TACO. <A & <T is 1 pair of base angles of TACO. <A congruent <T <ACO & <TOC is pair of base angles of TACO. <ACO congruent <TOC Reasons: Given Given Definition of Isosceles Trapezoid Definition of Trapezoid Base Definition of Base Angle Definition of Isosceles Trapezoid Definition of Base Angles Definition of Isosceles Trapezoid

  4. Constructing the Median a of Trapezoid • Draw a trapezoid of any size or shape. • Label the vertices ZOID with legs ZD and OI • Bisect the legs by making arc marks on both sides of each leg then connecting the two points made by the arc marks • Connect the points of intersection on the two legs
