Ram and Shyam looked at a window and made the following statements:
Ram: The bars in the window make right angle.
Shyam: The bars in the window make acute angle.
Ram is correct, Shyam is incorrect.
As clear by the figure given in the question that the bars are making an angle of 90° with each other; hence they are making a right angle. You can measure the angle with a protector and see for yourself that Ram is correct.
