The figure will be back where it started.
The figure will be back where it started.
The figure will be upside down.
The figure will be upside down.
The figure will be in the same quadrant but facing the opposite way.
Yes, reflection preserves the size of the figure.
Apologies for the incorrect response. Let's correct it.
The correct vertices after translating the triangle 3 units up are:
(-3, 5), (0, 8), and (4, 5)
The area of the translated square can be determined by calculating the area of the original square. Since the original square has sides of 5 units, its area is 5 * 5 = 25 square units.
Therefore, the area of the translated square will also be 25 square units.
