Answer:
y = 0
Step-by-step explanation:
A parallelogram is a quadrilateral with opposite sides parallel. Then segment CD must be parallel to AB, and CB must be parallel to DA. Two different segments are parallel if they have the same slope.
slope of DA = (yA - yD)/(xA - xD) = (4 - 2)/(1 - (-1)) = 1
slope of CB = (yB - yC)/(xB - xC) = (2 - yC)/(1 - (-1)) = 1
(2 - yC) = 2 * 1
2 - 2 = yC
0 = yC
Note: coordinates of A are (xA, yA), of B are (xB, yB), of C are (xC, yC) and of D are (xD, yD)
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can simply subtract the area of the small square from the area of the rectangle
A=8(12)-4(4)
A=96-16
A=80cm^2
Move the triangle to the right 3 and down 5
Perpendicular lines are lines that intersect and parallel line are lines that are parallel to each-other and never intersect
