Question

determine if the two figures are congruent and explain your answer. if they are congruent, tell which rigid motions were used.

Answer 1

@ganeshie8 last question

Answer 2

what do you think ?

Answer 3

are the corresponding side legnths same ?

Answer 4

yes

Answer 5

how do u know the lengths are same ? did u use distance formula ?

Answer 6

yeah

Answer 7

actually I honestly don't know, im really tired my brain cant function

Answer 8

you're right, the triangles are congruent because all the side lengths are same

Answer 9

can you show the steps to find the side lengths?

Answer 10

you may not be required to show the steps for side lengths, just explain that the side lengths are same from the diagram because each side is occupying the same number of grids

Answer 11

next, the transformations involved would be :
1) horizontal translation using rule : (x, y) --> (x+4, y)
2) reflection about x axis usign rule : (x, y) --> (x, -y)

Answer 12

see if they make sense

Answer 13

okay so the answer for this will be:
the triangles are congruent because all the side lengths are same.the side lengths are same from the diagram because each side is occupying the same number of grids.
the transformations involved would be :
1) horizontal translation using rule : (x, y) --> (x+4, y)
2) reflection about x axis using rule : (x, y) --> (x, -y)

Answer 14

that looks good, just explain more if you can

Answer 15

thanks for all your help
