The sum of the adjacent angles formed by a ray standing on a straight line is equal to right angles.
- When a ray stands on a line, two adjacent angles get formed.
- We know that the angle of a straight line is 180°.
- When a ray stands on a straight line, it divides the angle of a straight line equally.
- Or the ray stands on the straight line is a perpendicular line.
- Thus, the two adjacent angles are right angles.
- So, the total angle = 90° + 90°, two right angles.
