Suresh and Ramesh saw two perpendicular lines, and made the following statements:
Suresh: If two lines are perpendicular then the number of right angles formed between them is 2.
Ramesh: If two lines are perpendicular then the number of right angles formed between them is 4.
Suresh is incorrect, Ramesh is correct.
There are four quadrants made by two perpendicular lines. Now, in each quadrant, the angle made by the two lines is 90°. Therefore, total number of right angles = 4.
