If the sides of a triangle are in A.P. and one angle is  , then the ratio of the sides of the triangle:

A square is inscribed in the circle  and its sides are parallel to the coordinate axes then one vertex of the square is :

If two circles  and  intersects in two different points, then:

From point P(4,3) tangents, PA and PB are drawn to the circle . Then the area of the triangle PAB is :

the coordinates of the point from which the length of tangents to the three circles:

, ,  are equals is:
