    Study Notes

    Rectangle Theorems

    • Rectangles have congruent diagonals. This means their diagonals are equal in length.
    • This is helpful to calculate diagonal lengths and confirm rectangle characteristics.

    Rhombus Theorems

    • Rhombus diagonals intersect at right angles (90°).
    • Rhombus diagonals bisect each other.
    • Each diagonal of a rhombus bisects two opposite angles.
    • Useful for calculating angles, lengths & confirming rhombus properties.

    Isosceles Trapezoid Theorems

    • Isosceles trapezoids have congruent base angles.
    • If a trapezoid's base angles are congruent, it's an isosceles trapezoid.
    • Isosceles trapezoids have congruent diagonals.
    • If a trapezoid's diagonals are congruent, it's an isosceles trapezoid.
    • This helps determine angle and diagonal relationships.

    Triangle Theorems

    • A triangle's midsegment is parallel to the base and half its length.
    • This is useful in calculating lengths and confirming triangle relationships.

    Trapezoid Theorems

    • The median of a trapezoid is parallel to its bases and equals half their sum.
    • This aids in calculating median lengths.

    Kite Theorems

    • Kites have perpendicular diagonals.
    • Kites have exactly one pair of congruent opposite angles.
    • This helps verify kite properties and examine relationships.
