Answer:
Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals
Step-by-step explanation:
In Quadrilateral ABCD with points A(-2,0), B(0,-2), C(-3,-5), D(-5,-3)
Using the distance formula
d = sqrt(x2-x1)^2+(y2-y1)^2
|AB| = sqrt(0-(-2))^2+(-2-0)^2 = sqrt(8) = 2sqrt(2)
|CD| = sqrt(-5+3))^2+(-3+5)^2) = sqrt(8) = 2sqrt(2)
|BC| = sqrt(-3-0))^2+(-5+2)^2 = sqrt(18) = 3sqrt(2)
|AD| sqrt(-5+2)^2+(-3-0)^2 = sqrt(18) = 3sqrt(2)
Since |AB| is congruent to |CD| and |BC| is congruent to |AD|, we conclude that opposite sides are congruent.
Next, let us consider the slope.
Slope of |AB| = _-2-0_______ =__-2__ = -1
0-(-2) 2
Slope of |BC| = __-5+2___ = _-3___ = 1
-3-0 -3
Since the slopes of consecutive sides are opposite reciprocals, therefore ABCD is a rectangle.
In this exercise we have to use the knowledge of triangles to calculate the opposite and congruent sides, in this way we find that:
Since |AB| is congruent to |CD| and |BC| is congruent to |AD|, we conclude that opposite sides are congruent.
So using the data informed in the exercise statement, we have that:
- A(-2,0),
- B(0,-2),
- C(-3,-5),
- D(-5,-3)
Using the distance formula:
[tex]d = \sqrt{(x_2-x_+1)^2+(y_2-y_1)^2} \\|AB| = \sqrt{(0-(-2))^2+(-2-0)^2} = 2\sqrt{2}\\|CD| = \sqrt{(-5+3))^2+(-3+5)^2)} = 2\sqrt{(2)}\\|BC| = \sqrt{(-3-0))^2+(-5+2)^2} = 3\sqrt{(2)}\\|AD|= \sqrt{(-5+2)^2+(-3-0)^2} = 3\sqrt{(2)}[/tex]
