Answer

Quadrilateral LMNO is a square.

Solution

To classify quadrilateral LMNO with vertices , , , and , we can analyze the side lengths and slopes:
  1. Calculate Side Lengths:
    • LM:
    • MN:
    • NO:
    • OL:
    All sides are equal in length, suggesting a rhombus or square.
  2. Calculate Slopes:
    • Slope LM:
    • Slope MN:
    • Slope NO:
    • Slope OL:
    Adjacent sides have slopes that are negative reciprocals, indicating perpendicularity. Hence, all angles are right angles.
  3. Check Diagonals:
    • Diagonal LN: Length and slope (horizontal).
    • Diagonal MO: Length and undefined slope (vertical).
    The diagonals are equal in length and perpendicular, confirming that the quadrilateral is a square.
Answer:
c Square

The Deep Dive

To classify quadrilateral LMNO, we first calculate the lengths of its sides and examine its diagonals. The lengths of the sides provide information about parallelism and equality, which are key traits for classification. By finding the distances between each pair of points, we can determine that sides LM and ON are equal, as are the lengths of LO and MN, indicating a special shape.
Additionally, checking if the diagonals intersect at their midpoints can further reveal if this quadrilateral is a parallelogram. However, because one pair of opposite sides is equal and not parallel, the best classification for quadrilateral LMNO is a kite, as it has two pairs of adjacent sides that are equal in length without opposing sides being congruent.
The classification of quadrilaterals can also be determined by the characteristics of their angles. For instance, a kite has congruent angles between unequal pairs of sides, which adds to its distinct form. While a parallelogram features opposite sides that are equal and parallel, knowing these criteria helps you navigate through geometry with confidence!
