Triangle abc has vertices at a(3 , 7), b(5, 7), and c(3, 1). which statement proves that triangle abc is a right triangle?

There are no answer selections, but line x=3 is perpendicular from line y=7, so a right angle is formed as shown in the graph below.

Step-by-step explanation:

Step-by-step explanation:

AB is a horizontal line, and AC is a vertical line.

The intersection of AB and AC is a right angle; therefore, triangle ABC is a right triangle.
