Astudent claimed that the transformation (x, y) (3x, y) is a rigid motion because the segment joining (4,0) to (4,2) is transformed to the segment joining (12,0) to (12,2) and both of these segments have the same length complete the explanation of the students error

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

um is there supposed to be a picture?
