Question

Describe the transformations that map triangle A to triangle A'.

A) Translate 7 units to the left and then reflect over the x-axis.
B) Translate 5 units to the left and then reflect over the x-axis.
C) Translate 7 units to the right and then reflect over the x-axis.
D) Translate 5 units to the right and then reflect over the x-axis.

Answer 1

To map triangle A to triangle A', perform a translation by 7 units to the left and then reflect over the x-axis.

Step-by-step explanation:

To map triangle A to triangle A', we need to perform a translation and a reflection. Looking at the options given, the correct transformations are:

1. Translate 7 units to the left: This means moving each point of triangle A 7 units to the left.
2. Reflect over the x-axis: This means flipping triangle A' over the x-axis so that points below the x-axis move above the x-axis and vice versa.

Therefore, the correct answer amongst the given options is option A) Translate 7 units to the left and then reflect over the x-axis.
