Answer:
a reflection over the y-axis
Step-by-step explanation:
When a point is reflected over the y-axis, the images forms where the y-coordinate remains the same while the x-coordinate is transformed to the opposite sign.
In this case, a point (x,y) transforms to (-x,y). From the coordinates given;
(-3,3) --------(3,3)
(-1,3)----------(1,3)
(-2,1)----------(2,1)
See attached plot of object points and image points.

Answer:
third side = 4
Step-by-step explanation:
third side is hypoenuse as it is opposite to 90 degree.
using pythagoras theorem
(perpendicular)^2 + (base)^2 = (hypotenuse)^2
2^2 + (2 )^2 = hypotenuse^2
4 + 4*3 = hypotenuse^2
16 = hypotenuse^2
= hypotenuse
4 = hypotensue
