Question

Help and Please check this! I will medal:)

Answer 1

Need help?

Answer 2

Yes, with part A. And then just check part B:) @3mar

Answer 3

Ok

Answer 4

What do you think?

Answer 5

I see a reflection across the y-axis then a translation down 4 units

Answer 6

For part A
I will explain based on point A
A(-4,4) -->A' (4,0)
Since the transformation has changed the values not only the signs that means it involves a translation. But before that it involved reflection by the y axis how we know? Because the sign of x values were reverseD
So 1st transformation is reflection across y axis
A(-4,4) --> y axis reflection --> (4,4)
Now the end point was (4,0) that means a translation of law (x, y - 4)
Apply that
(4,4) --> (4,0) that means we are right since we achieved the same results

Answer 7

I would not answer congruent with congruent. Say what congruent is... same lengths and angles therefore congruent.

Answer 8

For B they are congruent because the side measures were kept the same. However if a dilation was applied the figures would not be congruent but that's not the case here. Da transformations of reflection and translation keeps the measurements of a figure as the original which means they would be congruent

Answer 9

thanks! what do you mean that you wouldn't answer with congruent @triciaal

Answer 10

@milo123
question: are they congruent?
Answer "After a rigid transformation... the figues are congruent"
did not explain that congruent because the same size and angle for a rigid transformation.

Answer 11

oh ...
