Question

6. In the given figure, AB = CB and AD = CD.
Prove that <3 = <4.
​

Answer 1

Step-by-step explanation:

IN TRIANGLE ABC

BECAUSE OF AB=CB

SO angle BAC=angleBCA

AGAIN IN TRIANGLE ADC --

angleDAC=angle DCA(BECAUSE OF AD=DC

HENCE

angle BAC=angle BCA

AND,

ANGLE DAC=angle DCA

SO WE CAN WRITE,

angle BAC- angle DAC=angle BCA-angle DCA

BASICALLY

angle BAC- angle DAC=3

AND,angle BCA-angle DCA=4

so ,3=4 here(proved)
