I can construct a quadrilateral by joining triangles. I will need a minimum of two triangles.
If I draw a quadrilateral and then draw all its diagonals. How many triangles will I find?
If the intersection points of angle bisectors of adjacent vertices of a quadrilateral are joined together to form a quadrilateral, then this quadrilateral will be
If two diameters of a circle intersect each other at right angles, then quadrilateral formed by joining their end points is a
