Question

triangle abc is transformed to form triangle abc. a is at (3, 1), b is at (1, 8), and c is at (7, 2). which transformation happened to △abc to form △abc? drag and drop the correct answers into the each box to complete the sentence. △abc is translated to form △abc

Explanation:

Step1: Identify coordinates of $A'$

From the graph, $A'$ is at $(- 2,-1)$.

Step2: Calculate horizontal and vertical change for point $A$

For point $A(3,1)$ to $A'(-2,-1)$, the horizontal change $x=-2 - 3=-5$ (left - shift), and the vertical change $y=-1 - 1=-2$ (down - shift).

Answer:

$\triangle ABC$ is translated $5$ units left and $2$ units down to form $\triangle A'B'C'$
