The correct option is
Further explanation:
Given:
The given figure is redrawn and attched in the end as Figure 1.
The two triangles are and as shown in attached Figure 1.
Calculation:
A reflection of line is defined as a mirror line or axis of symmetry.
In reflection, if the shape and size of an image is exactly same the original object, then it is called isometric reflection.
Reflection in a coordinate plane:
If we reflect a point across the -axis, then the coordinate remain same but the value of coordinate will change and transformed into its opposite that means its sign changes.
If we reflect a point across the -axis, then the value of coordinate remain same but the value of coordinate will change into its opposite sign.
Consider the attached Figure 1, and the coordinate point of the and are as follows:
From the above points we can see that there is only change in the value of coordinate and no change in the value of coordinate in the reflection.
So it can be said that the is congruent to and we can map to using a reflection across the -axis, which is a rigid motion.
Therefore, the correct option is .
