Relates the projection of a median and the sides of an arbitrary triangle

Calculates the Tangent value of angle θ(in degrees). The tangent of an angle is the ratio of the length of the opposite side to an acute angle of a right ... more

The surface of a right regular pyramid can be calculated by the area and the perimeter of the base and the slant height

Stewart’s theorem yields a relation between the length of the sides of the triangle and the length of a cevian of the triangle. A cevian is any line ... more

The altitude of a triangle is the distance from a vertex perpendicular to the opposite side. There is a relation between the altitude and the sides of the ... more

The radius of the inscribed circle of an arbitrary triangle is related to the altitudes of the triangle
