which Quadrilateral is it ?!
By: Brittani and Deziure
First we had to plot the points
Then find the slope of each side of the shape
From points A,D
are the sides parallel or perpendicular ?
They are parallel because C,D and A,B slope = -1 and A,D and B,C = 1
distance between C,D
Distance between A,D
distance between B,A
Distance between B,C
find the area of the shape
To find the area I multiplied the b*h
Find the midpoints of the each side of the rectangle
A,D midpoint
(2.5,1.5)
Distance between E,G
Distance between G,H
distance between F,H
Distance between E,F
Conclusion
we found that our new shape was a rhombus , because the both pairs of opposite sides are parallel and that all 4 sides of the shape are congruent.
Perimeter of the new shape
The perimeter of the new shape is 10 , we found the perimeter by adding all the lengths of sides together
