Answer:

Hey! I think I can help.

Parallel lines are lines that can't meet.Perpendicular lines are lines that can meet.

e.)Since the line at 12 and the line at 9 meets then it is a perpendicular line.

c.)Perpendicular line.

a.)Perpendicular line.

b.)Parallel line.

d.)Depending on how they are faced if the ends of the telephone wire meets the second one then it is perpendicular but if not then it is parallel that's if they are in different directions which they can not meet.Thank you for the question

Qaudriladrial ABCD had cordinates A (3, 5) B(5, 2) C(8, 4) D(6, 7) qaudriladrial ABCD is a what?

Lorico [155]

The quadrilateral is a square

<h3>What are quadrilaterals?</h3>

Quadrilaterals are polygons, that have four sides and four corners

The coordinates are given as:

A = (3, 5)
B = (5, 2)
C = (8, 4)
D = (6, 7)

Start by calculating the adjacent side lengths using:

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

So, we have:

$AB = \sqrt{(3- 5)^2 + (5- 2)^2}$

$AB = \sqrt{13}$

$BC = \sqrt{(8- 5)^2 + (4- 2)^2}$

$BC = \sqrt{13}$

The side lengths are equal.

Hence, the quadrilateral is a square
