Answer:
isosceles trapezoid
Step-by-step explanation:
1) find the distance of the points
AB =
BC = |7-4| = 3
CD =
AD = |9-2| = 7
2) equation of the line that passes threw BC
y = 7
3) equation of the line that passes threw AD
y = 5
conclusion
the quadrilateral has two parallel sides and two congruent sides, so it is a isosceles trapezoid
