    Study Notes

    Trapezoids and Kites

    • Trapezoids and kites are quadrilaterals that are not parallelograms.
    • A trapezoid is a quadrilateral with exactly one pair of parallel sides.
    • The parallel sides of a trapezoid are called bases.
    • The non-parallel sides of a trapezoid are called legs.
    • Base angles are angles formed by the base and a leg.
    • Specific types of trapezoids include isosceles trapezoids which have legs of equal length. The base angles of equal measure.

    Learning Objectives

    • Students will apply the Midline Theorem to solve problems involving triangles.
    • Students will prove theorems of trapezoids and kites.
    • Students will solve problems involving parallelograms, trapezoids, and kites.

    Review of Quadrilaterals

    • All quadrilaterals have four sides.
    • Squares are a specific type of rectangle.
    • Parallelograms have two sets of parallel sides.
    • Rectangles have four right angles.
    • Squares have four equal sides.
    • Opposite sides of a parallelogram are equal in length.
    • Consecutive angles in a parallelogram have a sum of 180 degrees.
    • The diagonals of a parallelogram intersect at their midpoints.
    • A diagonal divides a parallelogram into two identical triangles.

    Trapezoid Midsegment Theorem

    • A trapezoid's midsegment is parallel to its bases and has a length equal to half the sum of the lengths of its bases.
      • e.g., EF = 1/2 (BC + AD)

    Triangle Midsegment Theorem

    • A triangle's midsegment is parallel to the third side and is half its length.
      • e.g., TU = 1/2 (NV)

    Kite Properties

    • A kite's diagonals are perpendicular.
    • One diagonal of a kite bisects the other.
    • The non-vertex angles of a kite are congruent.

    Kite Area

    • The area of a kite is one-half the product of the lengths of its diagonals.

    Example Problems

    • Example problems demonstrate how to calculate the lengths of midsegments and bases, and apply the theorems. These involve identifying congruent parts, finding missing values, and solving for unknown variables. The use of equations and geometric principles are shown.
    • The length of one base of the trapezoid is double the length of the other base.
    • Example problems to solve find unknown values/lengths, and find area given values.
