Two perpendicular lines intersect. What is the measure of each angle formed?

Explanation:
When two lines are perpendicular, they meet to form right angles. A right angle measures 90 degrees. At the intersection of perpendicular lines, four angles appear, and each one is a right angle, so every angle formed is 90 degrees. The other numbers don’t fit because 45 and 60 are acute angles, asking for smaller turns, while 180 degrees is a straight line, which would not create the cross shape seen with perpendicular lines.
