Question

Triangle STU is located at S (2, 1), T (2, 3), and U (0, -1). The triangle is then transformed using the rule (x-4, y+3) to form the image S'T'U'. What are the new coordinates of S', T,' and U'? Describe what characteristics you would find if the corresponding vertices were connected with line segments.

Answer 1

Please help me.

Answer 2

Answer 3

start with the point S(2, 1) apply the rule S'( 2 - 4, 1 + 3) so S'(-2, 4)

the same rul needs to be applied to T and U. Subtract 4 from the x value and add 3 to the y value

Answer 4

So S' (-2,4) T' is (-2,6) U' is (-4,2)

Answer 5

that's correct

Answer 6

if you join the vertices, the triangles will be congruent

Answer 7

applying the rule to each point means the shape maintains its size and shape..

Answer 8

I got this

Answer 9

well the triangles seem to be a little out of sync.

Answer 10

Oh, hehe I see what I did wrong. So what next?

Answer 11

all you need to do to finish your question is recognise that applying the same rule to each vertex allows toe shape to keep its original size and shape... so the 2 triangles are congruent
