How Do You Classify Quadrilaterals?

Determine all the possible names that could be given to a quadrilateral

Summary

  1. Any figure with exactly 4 sides is called a quadrilateral
  2. Every type of figure on here is a type of quadrilateral
  3. Congruent sides have the same length
  4. If parallel sides are drawn as lines they would never intersect
  5. Each side of a rhombus must be the same length
  6. Right angles are angles that have a measurement of 90 degrees
  7. A square is a rectangle with all its sides congruent

Notes

    1. A quadrilateral is a figure with four sides
    2. A parallelogram is a four sided figure whose opposite sides are parallel and congruent
    3. A rhombus has four congruent sides
    4. A rectangle has four right angles
    5. A square has four right angles and four congruent sides
    6. A trapezoid has exactly one set of parallel sides
    1. As you're about to see, there are multiple ways to name the same figure
    1. The figure is a quadrilateral because it has 4 sides
    2. It's also a parallelogram because both pairs of opposite sides are parallel and congruent!
    1. The figure is a quadrilateral because it has 4 sides
    2. It's also a parallelogram because both pairs of opposite sides are parallel and congruent
    3. All of its sides are equal, so that makes this a rhombus
    4. The little box in the corner means the angle is a right angle
    5. This figure has 4 right angles, so it must be a rectangle
    6. Since it has 4 equal sides and 4 right angles, this figure is a square!
    1. This figure has 4 sides, so it must be a quadrilateral!
    2. Only one pair of this figure's opposite sides are parallel, so this is a trapezoid
    1. This figure is JUST a quadrilateral
    2. This figure doesn't have any right angles, so it can't be a rectangle or square
    3. None of its sides are equal, so it can't be a rhombus
    4. None of its sides are parallel, either, so it's not a parallelogram or trapezoid!
