In the right triangle, B is a point on AC such that .AB AD BC CD+ = + If ,AB x BC h= = and ,CD d= thenfind x (in term of h and d).

ABCD is a trapezium in which AB||DC and AD = BC. If P, Q, R, S be respectively the mid points of BA, BD, CD and CA, then PQRS is a

ABC is an isosceles triangle with AB = AC and AD ⊥ BC. Is ∆ADB ≅ ∆ACD ?

Question No 48.In right ΔABC, where ∠C is the right angle, point D lies on side AB, and point E lies on side BC such that AC = CD, DE = EB, and the ratio AC : DE = 4 : 3. What is the ratio AD : DB?

ABC triangle right angled at C. A line through the midpoint M of hypotenuse AB andparallel to BC intersects AC at D. (4)Show that:i) MD II BCii) CM = MA = ½ABiii) D is the midpoint of AC.

In the given figure A, B, C and D are collinear points. If AC = 3 cm, BD = 4 cm andBC = 2 cm, then AD is
