Question

anyone really good at geometry? I need help with a few questions.

Answer 1

The questions being...?

Answer 2

What set of reflections would carry hexagon ABCDEF onto itself?

Answer 3

@hihi67

these are the answers:
x-axis, y=x, x-axis, y=x

y=x, x-axis, y=x, y-axis

y-axis, x-axis, y-axis

x-axis, y-axis, y-axis

i think it's the second one?

Answer 4

Yes, the second one is correct.

Answer 5

@hihi67

Which two transformations are applied to pentagon ABCDE to create A'B'C'D'E'?

translated according to the rule (x, y) →(x + 8, y + 2) and reflected across the x-axis

translated according to the rule (x, y) →(x + 2, y + 8) and reflected across the y-axis

translated according to the rule (x, y) →(x + 8, y + 2) and reflected across the y-axis

translated according to the rule (x, y) →(x + 2, y + 8) and reflected across the x-axis

i think this would be the third answer? :3

Answer 6

correct again

Answer 7

@hihi67

What is the line of reflection between pentagons PQRST and P'Q'R'S'T'?

y = x

y = 0

x = 1

x = 0

would this be the second answer?

Answer 8

Yes, geez, this is pointless! You just keep getting them all right! :)

Answer 9

@hihi67

well, first time I took this I bombed it pretty bad. So i've been studying and I think I have it pretty well this time.. I just wanna make sure.

Answer 10

Yep, you're good.

Answer 11

Okay, there's one more I'll need help with.

Answer 12

A city grid of Anytown, USA is shown on the grid below. The fire department is represented by quadrilateral RSTU. Another fire department is opening in a different part of the city to maximize fire protection. The size of the new department's property must be congruent to the older department. Vertices A and B are plotted on the grid to represent two vertices of the new fire department quadrilateral ABCD.

What could be the ordered pairs representing vertices C and D of quadrilateral ABCD so that the new fire department is congruent to the old fire department?

Answer 13

C(1, 1), D(4, 1)

C(1, 6), D(4, 6)

C(1, 2), D(4, 2)

C(1, 4), D(4, 4)
