11.d is a point on the side of triangle abc, such that angleadc=anglebac. show that ca^2=cb. cd

Question is Incomplete,Complete Question is below.

D is a point on the side BC of a triangle ABC such that angle ADC = angle BAC Show that CA square=CB .CD

The Proof is given below.

Step-by-step explanation:

Given:

In ΔABC,

∠ADC = ∠BAC

To Show:

Proof:

In ΔBAC and ΔADC

∠ADC = ∠BAC ............................Given

∠C = ∠C .....................................Reflexive Property

∴ ΔBAC ~ ΔADC .................... A-A similarity test

If two triangles are similar then their sides are in proportion.
