ABC is a triangle in which AB = AC = 4 cm and `/_A = 90^@` .Calculate Area of ΔABC

Construct a triangle ABC in which AB= BC = 6.5 cm and CA = 4 cm . Also name the kind of triangle drawn .

The area of triangleABC is 8 cm^2 in which AB = BC = 4 cm and angleA = 90^@

ABC is an isosceles triangle in which AB = AC. If D and E are the mid-points of AB and respectively, prove that B,C,D and E are concyclic.

Construct a triangle ABC, given that AB = 5 cm, BC = 6 cm and AC = 7 cm

Construct a triangle ABC in which BC = 7cm, angle B = 75^@ and AB + AC = 13 cm .

Construct a triangle ABC in which BC = 8 cm , angleB = 45^@ and AB - AC = 3.5 cm .

ABC is a triangle in which altitudes BE and CF to sides AC and AB are equal. Also DeltaABE ~= DeltaACF . Then triangle ABC is :

ABC is a triangle in which altitudes BE and CF to sides AC and AB are equal. Also DeltaABE ~= DeltaACF . Then triangle ABC is :

In figure, ABC is a triangle in which angle ABC gt 90^(@) and AD bot CB produced. Prove that AC ^(2) = AB ^(2) + BC ^(2) + 2 BC BD.
