Example 1
Quadrilateral has vertices , , , and . Using slope, distance, and/or midpoints, classify quadrilateral as a rectangle, rhombus, square, trapezoid, isosceles trapezoid, or kite.
- Graph the quadrilateral.
- Calculate the slopes of the sides to determine if opposite sides are parallel.
- Examine the slopes of the consecutive sides to determine if they intersect at right angles.
- Calculate the lengths of the sides.
- Summarize your findings.
