Question

If triangle ABC is congruent to triangle DEF, what would be the coordinate of F?
(6,3)

(7,3)

(6,4)

(7,4)

Answer 1

could you look at a few more?

Answer 2

Triangle DOG is transformed using a reflection
Which could be coordinates of D'O'G' after the reflection?

D=(0,0), O=(-1,-2), G=(1,4)

D=(0,0), O=(-1,-2), G=(1,-4)

D=(0,0), O=(-2, 1), G=(-1, -4)

D=(0,0), O=(-1,2), G=(1,4)

Answer 3

Draw a line that is parallel to BC and crosses E. Then place F so that BC=EF

Answer 4

That was for the first prob

Answer 5

thank you !

Answer 6

yw. As for the second you can obtain the reflection by drawing points symmetrical to the y-axis

Answer 7

i dont get it >.<

Answer 8

For example A(2;1) -> A'(-2;1)
an other example B(-5;2) -> B'(5;2)
Generally C(x;y) -> C'(-x;y)

Answer 9

ohhh okay !
