Fun Fact: Did you know that parallelograms are used in architecture all the time? They provide structural stability and can be found in bridges, buildings, and even furniture!
Rectangles are special parallelograms where all angles are right angles (90 degrees). This gives them some extra cool properties:
Example: If you know the length of one diagonal of a rectangle, you automatically know the length of the other diagonal! Super useful for solving problems quickly.
Squares are the rockstars of the quadrilateral world! They're rectangles with all sides equal. This means they inherit all the properties of parallelograms, rectangles, and rhombuses (which we'll get to next!).
Interesting Fact: The ancient Greeks considered the square to be the most perfect shape, representing balance and harmony.
A rhombus (plural: rhombuses or rhombi) is a parallelogram with all sides equal. It looks like a diamond, but don't let its flashy appearance fool you – it has some serious math power!
Example: If a rhombus has an angle of 80 degrees, the diagonal that cuts through that angle will split it into two 40-degree angles. Knowing this can help you find other angles in the shape.
Trapeziums (also called trapezoids) are quadrilaterals with only one pair of parallel sides. They're a bit different from the other shapes, but still important to understand.
Example: If a trapezium has angles of 70 and 110 degrees on one of its non-parallel sides, you know you're on the right track because they add up to 180 degrees.
