Complete the coordinate proof of the theorem. Given: A B C D is a rectangle. Prove: The diagonals of A B C D are congruent.

Inessa05 [86]

Step-by-step explanation:

Given coordinates of the rectangle ABCD:

A(0, 0), B(a, 0), C(x, y), D(0, b)

Lets first find coordinates of C

We can see that A and B are on same line horizontally, so C and D will be on the parallel line

The distance AB and CD are equal also distance AD and BC are equal, therefore

AB = a - 0 = a, CD = a
AD = b - 0 = b, BC = b

So the coordinates of C are:

x = a, y = b

Now the diagonals:

AC = √(a-0)² + (b-0)² = √a²+b²
BD =√(0-a)² + (b -0)² = √a² + b²

Since AC = BD, we can state they are congruent

Find the distance between the points (3,0) and (-1,-5)

nadya68 [22]

Answer:

6.4

Step-by-step explanation:

distance formula $\sqrt{(x2-x1)^2+(y2-y1)^2}$

$\sqrt{(-1-3)^2+(-5-0)^2}$

$\sqrt{(-4)^2+(-5)^2}$

$\sqrt{16+25}$

$\sqrt{41}$ ≈6.403.......
