Reflection of Triangle in Coordinate Plane

Hard Geometry And Measurement Transformations

In a coordinate plane, a triangle has vertices at points A(2, 3), B(5, 7), and C(2, 10). The triangle undergoes a reflection over the line y = x.

What are the coordinates of the reflected vertices of triangle ABC?

A'(3, 2), B'(7, 5), C'(10, 2)

A'(3, 2), B'(5, 7), C'(10, 2)

A'(3, 2), B'(7, 10), C'(10, 2)

A'(3, 2), B'(7, 5), C'(2, 10)
