In `/_\ABC, AD is a perpendicular to BC.S.T iii) `AB + AC` gt `BC`

In /_\ABC, AD is a perpendicular to BC.S.T. i) AB gt BD ,

In /_\ABC, bar(AD) is a perpendicular to bar(BC) .S.T ii) bar(AC) gt bar(CD) ,

In /_\ABC , AD is the perpendicular bisector of BC. Show that /_\ABC is an isosceles triangle in which AB=AC.

/_\ ABC is right angled at A, AD is perpendicular to BC, AB= 5cm, BC= 13cm and AC= 12cm. find the area of /_\ABC . Also, find the length of AD.

In triangle ABC, D is mid point of BC, if 'AD' is perpendicular to 'AC then cos A cos C

In DeltaABC , the bisector AD of A is perpendicular to side BC Show that AB = AC and DeltaABC is isosceles.

In DeltaABC , AD is the perpendicular bisector of BC (See adjacent figure). Show that DeltaABC is an isosceles triangle in which AB = AC.

If in a /_\ABC , the bisector AD of angle A is perpendicular to side BC then /_\ABC is______ triangle.

In Delta ABC , D is the mid point of BC and AD is perpendicular to AC , then show that cos A cos C = ( 2 ( c^(2) - a^(2))/( 3ac)
