Question

59. If one of the angle of two intersecting lines is right angle then prove that
other three angles will also be right angles.​

Answer 1

the intersecting line makes four angles at the point of intersection whose total value is 360° .

so if 1 angle is 90 ° then the opposite Angle is also 90° as opposed angle are equal

so the remaining angle =180°

so these two angles are also equal so the angles are 180°/2=90°

so proved that all angles are 90°
