Could the lengths 18 in., 80 in., and 82 in. be the side lengths of a right triangle?

This is a right triangle

Step-by-step explanation:

We can check this using the Pythagorean theorem

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

18^2  + 80^2 = 82^2

324+6400=6724

6724 = 6724

True, so this is a right triangle

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
