# It is incorrect because angle GCD = 42°, angle GDC = 36°, and angle CGD = 102°.
# It is incorrect because angle GCD = 48°, angle GDC = 36°, and angle CGD = 96°.
# It is correct because angle GCD = 42°, angle GDC = 42°, and angle CGD = 96°.
# It is correct because angle GCD = 48°, angle GDC = 48°, and angle CGD = 84°.

anonymous · Answer

i think it is either b or c? because angle CGD is a 96 degree angle right?

anonymous · Answer

B. Is correct.

anonymous · Answer

It's B because by the triangle sum theorem and vertical angles, you can solve the other angles.

anonymous · Answer

ok are you sure?

anonymous · Answer

Yes. 200% sure :)

anonymous · Answer

ok thx

i thought it was a but im not sure

anonymous · Answer

Hold on. Let me solve it.

anonymous · Answer

k

anonymous · Answer

You are correct. You can solve it using AA similarity postulate.

The coordinates of the vertices of quadrilateral ABCD are A(3, 4), B(7, 4), C(1, 1) and D(1, 3).

ABCD is reflected across the x-axis to form PQRS. What is the length of diagonal PR?  (4 points)

    * √13 units
    * √37 units
    * 3√5 units
    * √53 units

anonymous · Answer

I know that a translation across the x-axis

    * (x, y) → (x, -y)

anonymous · Answer

and you would use the midpoint formula, but my answer wasn't a choice

anonymous · Answer

oops not midpoint i meant distance formula

anonymous · Answer

No picture?

anonymous · Answer

no :( they didnt give one

anonymous · Answer

It's either A or B, but I'm leaning more towards A.

anonymous · Answer

Yeah. I meant A before.

anonymous · Answer

thx
