Answer: OPTION A.
Step-by-step explanation:
By definition:
- When you reflect a figure, you flip it over a line of reflection, then, both figures will be in opposite directions.
- The image (which is the reflection) and the pre-image will have the same shape ad size.
- If a figure is reflected over the y-axis, then the sign of the x-coordinate is changed.
Keeping the above on mind, you can conclude that when a triangle is reflected over the y-axis the coordinates of the vertices are afectted as following:
- The y-coordinate is not changed.
- The sign of the x-coordinate is changed.
Then:
