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.

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.

just winging it 4 the last part, using ittt

then whats the answer??!

letsssgo they get what they get lmao

wow

1. By using the properties of perpendicular and parallel lines, we can determine that a polygon is either a rectangle or a trapezium.

2. Let's choose a rectangle as the type of quadrilateral.

To confirm that a given polygon is a rectangle using properties of perpendicular and parallel lines, together with slope, we need to consider the following properties:

a) Perpendicular lines: In a rectangle, all four angles are right angles (measuring 90 degrees). We can confirm the presence of right angles by finding the slopes of adjacent lines in the polygon and checking if they are negative reciprocals of each other. If the slopes satisfy this condition, we can conclude that the lines are perpendicular, which is a characteristic of a rectangle.

b) Parallel lines: In a rectangle, opposite sides are parallel to each other. To verify this property, we need to find the slopes of opposite sides of the given polygon. If the slopes are equal, we can conclude that the lines are parallel, which confirms the presence of a rectangle.

c) Slope: A rectangle is a special case of a quadrilateral where all sides are congruent and opposite sides are parallel. Slope can be used to determine congruency of sides. By calculating the slopes of the sides of the given polygon and confirming that they are equal, we can establish that the polygon satisfies this property.

By examining these properties of perpendicular and parallel lines, together with the concept of slope, we can determine if a given polygon is a rectangle.

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
