Imagine reflecting triangle ABC across line MN. Then answer the questions about the reflected figure.

triangle

Step-by-step explanation:

Reflection of an figure across any line is the mirror image of the figure.

That means reflection of a figure is a rigid transformation, in which size or shape of the image doesn't change.

Therefore, when we reflect triangle ABC across the line MN shape of the reflected angle will remain same as a triangle.
