Question

Find the lengths of the sides of a triangle with vertices: (0,0) (5,0) (5,12)

Answer 1

a. 5,12,12
b. 5,5,12
c. 5,12,5
d. 5,12,13

Answer 2

You can count units on the vertical and horizontal lengths.

That leaves one side to find. See attachment.

Answer 3

Answer 4

What is the distance from (5,12) to (0,0)?

Answer 5

idk

Answer 6

Well, you can learn the distance formula.

Answer 7

it's 13

Answer 8

I think it's D

Answer 9

Yes, I agree.

Answer 10

Generally 3-times use pythagorean theorem (from which is derived distance formula) to calculate side length. In this case, some sides lie on verictal or horizontal line, so length of oen side is |12-0| =12 and second |5-0|=5... third side must be "computed".
