Answer and Step-by-step explanation:

A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.

Definition 1: A parallelogram is a four sided figure where the opposite sides are parallel.

Theorem 1: In a parallelogram, the opposite sides are of equal length.

Theorem 2: If the opposite sides in a quadrilateral are the same length, then the figure is a parallelogram.

Theorem 3: A quadrilateral is a parallelogram if and only if the diagonals bisect each other.

Theorem 4: If one pair of opposite sides in a four sided figure are both opposite and parallel, then the figure is a parallelogram.

Definition 2: A rectangle is a quadrilateral where all four angles are the same size.

Theorem 5: A rectangle is a parallelogram.

Theorem 6: A rectangle is a parallelogram if and only if the diagonals are the same length.

Definition 3: A rhombus is a quadrilateral where all four sides have the same length.

Theorem 7: A rhombus is a parallelogram.

Theorem 8: A quadrilateral is a rhombus if and only if the diagonals are perpendicular bisectors of each other.

Theorem 9: A quadrilateral is a rhombus if and only if the diagonals bisect all the vertex angles.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
