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

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

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

In the given figure, /_\ ABC is an isosceles triangle in which AB - AC. If AB and AC are produced to D and E respectively such that BD = CE, prove that BE = CD. Hint. Show that /_\ ACD = /_\ ABE .

In Delta ABC , AD is the perpendicular bisector of BC (see Fig. 7.30). Show that Delta ABC is an isosceles triangle in which A B\ =\ A C .

In Delta ABC , AD is the perpendicular bisector of BC (see Fig. 7.30). Show that Delta ABC is an isosceles triangle in which A B\ =\ A C .

In Delta ABC , the bisector AD of angle A is perpendicular to side BC (see Fig. 7.27). Show that AB = AC and Delta ABC is isosceles.

In fig.30, find (i) /_ACD,( ii) /_AED

The vertices of a Delta ABC are A (-5,-1), B (3,-5) , C (5,2). Show that the area of the Delta ABC is four times the area of the triangle formed by joining the mid-points of the sides of the triangle ABC.

ABC is a triangle in which altitudes BE and CF to sides AC and AB are equal (See Fig. ). Show that AB = AC or DeltaABC is an isosceles triangle.
