Can 16,30,34 be a right triangle

let's check first is it Right Triangle because we can do it using Pythagorean theorem:

let's sides 16 and 30 be legs, and 34 hypotenuse

1156=1156...so, this is true and your triangle IS Right Triangle

but, it is also a scalene triangle with a right angle

Step-by-step explanation:

(4,2)

Step-by-step explanation:

THIS IS ASSUMING you are scaling it around 0,0

S is 2,1.

(x',y') = (2,1)

You want to find the coords with a scale factor of 2.

(x',y') = 2(2,1)

x',y' = 4,2

(4,2)
