what are the opposite angles of a rhombus

Two angles having a common vertex and a common arm, such that the other arms of these angles are on opposite sides of the common arm, are called adjacent angles. ..

A pair of angles are said to be alternate angles if (i) both are interior angles (ii) they are on the opposite sides of the transversal and (iii) they are not adjacent angles. Alternate angles are some times also called alternate interi..

Angle of Friction - Consider a block placed on a rough floor. Now, the reaction force is because it is equal and opposite to the weight . Now apply a horizontal force so that the block just begins to slide, i.e., the frictional force is equal to the limiting friction. When this ..

A Corollary is an easy consequence of a theorem. It two lines intersect, then the vertically opposite angles so formed are equal, and When a number of lines meet at a point, the sum of the angles so formed is four right angles..
