[" 6.In Fig."6" ."7" if "/_" ABE "=/_" ACD,show that "],[Delta ADE-Delta ABC" ."]

In Fig. If Delta ABE = ACD , show that Delta ADE ~ Delta ABC .

In Fig. 6.37, if Delta ABE~=Delta ACD , show that Delta ADE~Delta ABC .

In that figure, if Delta ABE ~= Delta ACD , show that Delta ADE ~= Delta ABC .

In Delta ABC , AB = AC and BC = 6cm, D is a point on the side AC such that AD = 5cm and CD = 4cm, show that Delta BCD ~ Delta ABC and hence find DB .

In the adjoining figure,E is a point on the median AD of a Delta ABC. Show that ar (Delta ABE)=(Delta ACE)

In a triangle ABC, AB = AC. Show that the altitude AD is median also.

AD is an altitude of an isosceles triangle ABC in which AB = AC . Show that , AD bisects BC

AD is an altitude of an isosceles triangle ABC in which AB = AC . Show that , AD bisects angle A .

ABC is an isosceles triangle, right-angled at B. Similar trianles ACD and ABE are constructed on sides AC and AB. Find ratio between the areas of Delta ABE and Delta ACD .

In Delta ABC, D and E are the midpoint of AB and AC respectively. Find the ratio of the areas of Delta ADE and Delta ABC .
