Answer
Two lines are called perpendicular if they intersect at right angles (90°).
(i) The adjacent edges of a postcard meet at right angles.
∴ Yes, they are models for perpendicular lines.
(ii) The line segments forming the letter 'L' meet at right angles.
∴ Yes, they are models for perpendicular lines.
(iii) The adjacent edges of a Math book meet at right angles.
∴ Yes, they are models for perpendicular lines.
(iv) The line segments forming the letter 'V' meet at an acute angle, not at a right angle.
∴ No, they are not models for perpendicular lines.
