Question

In the following graph, AABC is congruent to AA'B'C'. A teacher asks a student Janine to state the

translation rule for this transformation janine focuses on point and states that the translation rule is
(x,y) (x-2, y-6). In other words, to shift from the blue to the red triangle, you must shift each point two
units left and six units down

State whether Janine's answer was correct or incorrect. In at least three sentences, support your
response with a brief explanation. Be sure to use the term transformation in your explanation​

Answer 1

Janine's answer is incorrect.

Explanation:

Rigid transformations are methods by which the image of a given figure or object can be produced either by rotation, translation, dilation or reflection.

Since Janine used translation method for the transformation, the dimension of the shape is preserved but not its initial position. To translate AABC to AA'B'C', each point should shift three units left and five units down.

Therefore, the appropriate translation rule is:

(x, y) ⇒ (x + 3, y + 5)
