Isosceles TrapezoidQuadrilateral with only one pair of opposite sides parallel, and non‐parallel sides are congruent

Given the coordinates of four points, it is possible to determine which quadrilateral is being graphed:
Parallelogram1 ‐ slopes of both pairs of opposite sides are equal2 ‐ lengths of both pairs of opposite sides are equal3 ‐ diagonals intersect at each of their midpoints
Rectangle1 ‐ slopes of both pairs of opposite sides are equal2 ‐ slopes of consecutive sides are opposite reciprocals3 ‐ diagonals intersect at each of their midpoints4 ‐ diagonals are the same length

Kite1 ‐ slopes of both pairs of opposite sides are NOT equal
2 ‐ two pairs of consecutive sides have same length(but not all four the same)
3 ‐ slopes of diagonals are opposite reciprocals
Isosceles Trapezoid1 ‐ slopes of only one pairs of opposite sides are equal
2 ‐ other two sides are same length3 ‐ diagonals are the same length

Slope parallel and perpendicular segments
Distance lengths of segments
Midpoint bisected segments
