Angle of repose : it is the angle that the inclined plane makes with the horizontal when an object kept on it slides down the inclined plane.
μ= F/R F= force of limiting friction
R= normal reaction
μ= mgsinΦ/mgcosΦ
μ= tanΦ
But as we know that tanθ= μ
Thus Φ=θ
That means the angle of friction is equal to angle of repose
