1.Diagonals AC and BD of a trapezium ABCD with AB parallel to DC intersect at point O. Using similarity criterion theorem for two triangles show that diagonals of AB parallel to DC intersect at point O.
2.Prove that "the areas of two similar triangles are equal they are not concurrent".
3.ABC is an isoceles triangle right angled at C. Prove that AB2 = 2AC.
4. In a rigt angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides .
5.In triangle ABC if EF is parallel to AB and ar(triangle CEF) is congruent to ar(EFBA) then find the ratio of CA and EA.
