ABC is a right angled triangle in which `/_A = 90^@` and `AB = AC`. Show that `/_B = /_C`.

In the given figure ABC is a right triangle and right angled at B such that /_BCA = 2/_BAC. Show that hypotenuse AC = 2BC.

ABC is a right angled triangle which is right angled at C. Let AB=c, BC=a, CA=b and let p be the length of perpendicular from C and AB. Prove that c=(ab)/p .

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

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, (i) AD bisects BC (ii) AD bisects /_ A.

/_\ABC is an isosceles triangle with AB=AC. Draw AP _|_ BC to show that /_B=/_C

DeltaABC is an isosceles triangle in which AB = AC. Side BA is produced to D such that AD = AB (see figure). Show that /_BCD is a right angle.

If, in a right angled triangle ABC, the hypotenuse, AB = p, then AB.AC + BC . BA + CA. CB =

In right angle triangle ABC , /_ B = 90^@, tan c = 5/12 then the length of hypotenuse is .
