Kylie draws a triangle on a coordinate grid. She then performs the following transformations in the order below: • a translation of 3 units to the left
• a dilation by a factor of 3
• a reflection across the x-axis
• a rotation of 180°
She claims the resulting triangle is congruent to the original triangle.
Which of Kylie's four transformations should she not have done in order for her claim to be correct?
A
a translation of 3 units to the left
a dilation by a factor of 3
a reflection across the x-axis
O
a rotation of 180°
