Prove that that a triangle which has one of the angle as `30^0` cannot have all vertices with integral coordinates.

Show that the triangle which has one of the angles as 60^(@) can not have all verticles with integral coordinates.

prove that triangle must have atleast two acute angle

Prove that each angle of an equilateral triangle is 60^0

Let S be the set of all triangles in the xy-plane, each having one vertex at the origin and the other two vertices lie on coordinate axes with integral coordinates. If each triangle in S has area 50 eq. units, then the number of elements in the set S is

Prove that all the vertices of an equilateral triangle can not be integral points (an integral point is a point both of whose coordinates are integers).

Prove that the coordinates of the vertices of an equilateral triangle can not all be rational.

Two angles of a triangle are equal and the third angle is greater than each of those angles by 30^0dot Determine all the angles of the triangle.

Two angles of a triangle are equal and the third angle is greater than each of those angles by 30^0 determine all the angles of the triangle.
