Question

Two vertices of a right triangle have the coordinates (-2, 5) and (9,5)

What is the length of the side formed by these vertices?​

Answer 1

11

Explanation:

Note that the horizontal line y = 5 goes through both vertices, and that the length of the side formed by those vertices is the distance between the vertices in this case. That distance would be 9 - (-2), or 11.

Answer 2

The length of the formed by these vertices is 11 units.

Explanation:

We are given the following coordinates of two vertices of a right angled triangle and we are to find the length of the side formed by these vertices:

`(-2, 5)` and
`(9,5)`

Using the distance formula to find the side length:

Side length =
`\sqrt { ( 9 - ( - 2 ) ) ^ 2 + ( 5 - 5 ) ^ 2 }` =
`√(121)` = 11 units
