Answer:
The distance formula can be used to prove that a quadrilateral has congruent sides.
Step-by-step explanation:
If a line segment passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the distance between these two points is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It means the distance formula is used to find the length of a line segment.
Using distance formula we can find the length of each side of a quadrilateral and we can prove that whether a quadrilateral has congruent sides or not.
Therefore the distance formula can be used to prove that a quadrilateral has congruent sides.
