A quadrilateral is shown on the graph:

What effect will a reflection about the x-axis have on the quadrilateral? Be sure to address how it could impact the angles, side lengths, and congruency between the original pre-image and the image.

@AloneS i need help

alones · Answer

Reflect $\ (4,1)$ over that horizontal line to have it end up at $\ (4,-1)$
Another point on the given quadrilateral is $\ (2,2)$

misssmartiez · Answer

Reflecting arcoss the x axis, do you know what that means?

misssmartiez · Answer

across*

misssmartiez · Answer

The numbers or values in the 'x' place, have to be opposites. (Pre-image and image coordinates.)

alones · Answer

So if you reflect $\ (2,2)$ over the x axis, it lands on the point $(2 ,-2)$

alibaby · Answer

is that the answer @AloneS ?

misssmartiez · Answer

What is the 'x' value? Touching up what Alone said, 


(x,y)

you run before you jump.

x is running, y is jumping. Now, plug in the numbers that fall in those factor's places.

misssmartiez · Answer

Now, how would it EFFECT the quadrilateral?

misssmartiez · Answer

It wouldn't. Why? Its a rigid transformation.

misssmartiez · Answer

Rigid transformations do not change the original shape in size, measurement in length/angles, etc. The only thing changing is the position.
