In a fig. PA is a tangent to the circle. PBC is a secant & AD bisects angle BAC. Show that triangle PAD is an isosceles triangle.Also show that `/_CAD=1/2(/_PBA-/_PAB)`

In the figure PA is a tangent to the circle, PBC is secant and AD bisects angle BAC. Show that triangle PAD is an isosceles triangle. Also, show that: /_CAD=1/2[/_PBA-/_PAB]

In the given TA is a tangent to the cirlce and TBC is a secant. If AD bisects angle BAC, prove that: Delta ADT is isosceles.

In the figure,AB is a diameter PA is a tangent to the circle and PCB is a secant.Show that /_ABP=/_CAP

In Fig.10.64,BC is a tangent to the circle with centre O.OE bisects AP.Prove that Delta ABC-Delta AEO

As shown in the figure,PA is a tangent to a circle and PBC is a secant,so that PB=AB . Prove that PB.PC=AC^(2)

In a triangle ABC, side AC is greater than side AB and point D lies on side BC such that AD bisects angle BAC. Show that: angle ADB is acute.

In Delta ABC, AB =AC and D is a piont in side BC such that AD bisect angle BAC. Show that AD is perpendicular bisector of side BC.

AD is an altitude of an isosceles triangle ABCD which AB=AC. Show that AD bisects angleA

In the figure, angle D = angle E and (AD)/(DB) = (AE)/(EC) , prove that Delta BAC is an isosceles triangle

If acosA=bcosBthen show that the triangle is either an isosceles triangle or right angled triangle.
