Question

10. Show that the given points form a parallelogram :
A(2.5,3.5), B(10,- 4), C(2.5, -2.5) and D(-5,5)

Answer 1

Answer:

Yes given points make the parallelogram

Step-by-step explanation:

We are given that

A = (2.5,3.5), B = (10,- 4), C =  (2.5, -2.5) and D = (-5,5)

Since

AB = √((10 - 2.5)² + (-4 - 3.5)²) = 10.61 = CD

And

DA = √((- 5 - 2.5)² + (5 - 3.5)²) = 7.65 = CD

So

Given figure is the parallelogram
