Prove a quadrilateral with vertices g(1,-1), h(5,1), i(4,3) and j(0,1) is a rectangle., using rectangle method 1.

Steps explained below.

Step-by-step explanation:

It is given that the vertices of the quadrilateral are G(1, -1), H(5, 1), I(4, 3) and J(0, 1).

A parallelogram is a rectangle if one of its angle is 90° (and therefore, all angles will be 90°).

A quadrilateral is a parallelogram if two pairs of opposite sides are equal.

So, lets prove GH = IJ, HI = GJ and H = 90°.

= 20

= 20

Therefore, GH = IJ

= 5

= 5

Therefore, HI = GJ

Two pairs of opposite sides are equal and hence GHIJ is a parallelogram.

Now, in Δ GHI,

= 25

Therefore, .

This shows that Δ GHI is a right angled triangle and ∠ H = 90°.

Hence, GHIJ is a rectangle.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
