ABCD is a rectangle.
Explanation of Solution
Given data:
Formula used:
Slope intercept form:
Calculation:
For line AB,
Similarly for,
Line BC
Line CD
Line DA
As the line AB and CD have same slope so they are parallel to each other and similarly BC and AD are parallel to each other.
As the lines AB and BC have opposite slope so they are perpendicular to each other similarly BC ⊥ CD and CD ⊥ DA and DA ⊥ AB.
So ABCD is a rectangle.
Conclusion:
ABCD is a rectangle.
