If the arms of an angle on the paper are decreased the angle decreases.

If the arms of an angle on the paper are increased, the angle increases.

Prove that if the two arms of an angle are perpendicular to the two arms of another angle,then the angles are either equal or supplementary.

If the arms of one angle are respectively parallel to the arms of another angle, show that the two angles are either equal or supplementary.

If two adjacent sides of a square paper are decreased by 20% and 40% respectively, by what percentage does the new area decrease?

If two adjacent sides of asquare paper are decreased by 20% and 40% respectively, by what percentage does the new area decrease ?

IF the radius of the circular track decreases, then the angle of banking

If the arms of one angle are respectively parallel to the arms of another angle , then the two angles are :

Corresponding angles a pair of angles in which one arm of both the angles is on the same side of the transversal and their other arms are directed in the same sense is called a pair of corresponding angles.

CORRESPONDING ANGLES A pair of angles in which one arm of both the angles is no the same sides of the transversal and their other arms are directed in the same sense is called a pair of corresponding angles.
