angle is the basic part of triangle
The three basic ratios are sine, cosine and tangent.In a right angled triangle,the sine of an angle is the ratio of the lengths of the side opposite the angle and the hypotenuse;the cosine of an angle is the ratio of the lengths of the side adjacent to the angle and the hypotenuse;the tangent of an angle is the ratio of the lengths of the side opposite the angle and the the side adjacent to the angle.

Acute angle less than 90' Right angle 90' Obtuse angle 91-180 Reflex angle 181-360'
The basic friction angle for sandstone is 26 degrees to 35 degrees. This angle changes based on how wet the stone is.
Degrees, Radians or Grads
For rock, the basic friction angle is somewhat less than residual angle. The basic friction strength is that shear resiatance of two smooth surfaces. The residual shear atrength is that for two rough surfaces after long shearing. At residual state, the shear resistance almost keeps constant and no shear-dilation.
