1Slope and the properties of perpendicular and parallel lines can be used to confirm that a polygon is a specific type of quadrilateral.

What types of quadrilaterals can you determine by using these properties? List at least two types of quadrilaterals.

2Choose one type of quadrilateral from your answer to Question 1. Explain in complete sentences how you can use properties of perpendicular and parallel lines, together with slope, to confirm that a given polygon is the type of quadrilateral you chose. Be sure to clearly state the properties that you need to use.

I say a rectangle and a trapezium for the first part but dont know how to explain it.

1. if you have the slopes, then you can tell when two lines are parallel.
A rectangle has two pairs of parallel sides
A trapezium has exactly one pair of parallel sides

2. That literally has to be the worst response I have ever seen on Jiskha in the last 3 years I have been active on Jiskha. That gave no context whatsoever and I'm even more confused about the question than I originally was.
