Question

Use the distance formula to find the length of each side of the triangle.


Classify your triangle as scalene, isosceles, or equilateral. Show work or provide an explanation to justify this classification.

Answer 3

@shkrina It's not allowing me to upload the picture of my construction but the coordinates are: A (-4,-2) B (4,-2) C (0,4)

Answer 4

a scalene trigangle has three different sides therefore 3 different distances, an isocilies triangle has two same sides therefore two same distance and one different and equilateral triangle has to have all three sides to be same the distance for all there sides have to be equal

Answer 5

you will find the distance between a and b, b and c, and c and a
distnace formula is d=radical((x2-x1)^2+(y2-y1)^2)

Answer 6

My triangle is either isosceles or equilateral.

Answer 7

it depends on your distances of each of your 3 sides

Answer 8

I always fail at the distance formula

Answer 9

Can you help me? @coolaserman

Answer 10

If my coordinates are A (-4,-2) B (4,-2) C (0,4) is my triangle equilateral or isosceles?

Answer 11

sure so
in this case when finding AB B is your 2nd point
rad((4--4)^2+(-2--2)^2)
now for bc C is your second point
rad((4-4)^2+(0--2)^2)
and finally for ca a is your second point
rad((-4-4)^2+(-2-0)^2)
hope this helps
rad means radical

Answer 12

use the distance formula
