in any traingle ABC , 3 , 4 and 5 are the interior points on side AB , BC, and CA respectively . then total number traingle , consider these points as vertices, are

If the sides AB, BC and CA of a triangle ABC have 3, 5 and 6 interior points respectively, then the total number of triangles that can be constructed using these points as vertices, is equal to :

In a triangle ABC, points P, Q and R are the mid-points of the sides AB, BC and CA respectively. If the area of the triangle ABC is 20 sq. units, find the area of the triangle PQR

If DeltaABC is a equilateral triangle and P, Q, R are mid-points of sides AB, BC and CA respectively then-

In a triangle ABC,D and E are the mid- points of BC,CA respectively.If AD=5,BC=BE=4, then CA=
