Answer:
The correct option is B
B) Slope of AB = 2, Slope of BC = -1/2, Slope of CD = 2, and slope of of DA = -1/2
Step-by-step explanation:
A rectangle has the following features:
- Opposite sides are equal
- Opposite side are parallel (same slope)
- all the interior angle are 90° (adjacent sides are perpendicular)
Considering these point, the best options is B because:
AB || CD = opposite sides have same slope 2 (they are parallel)
BC || DA = opposite sides have same slope -1/2 (they are parallel)
For 2 lines to be perpendicular:
Slope of line 1 = -1/ (Slope of line 2)
Let line 1 be AB and line 2 be BC
Slope of AB = -1/(Slope of BC)
2 = -1/(-1/2 )
2=2
Hence proved
As two points are true, third point will also be true
