Question

hey mate need help ​

Answer 1

Try I hope you can do.

A hint: you first have to make two triangle congruent and then you have to equal AC=BD.Therefore, AC bisects BD

Answer 2

Answer:

GIVEN = BM AND DN ARE PERPENDICULAR TO AC

ALSO

BM = DN

TO PROVE = AC BISECTS BD

=> DO = BO

PROOF = IN TRIANGLE DON AND BOM

DN = BM (GIVEN)

ANGLE DNO = ANGLE BMO ( =90)

ANGLE DON = ANGLE BOM ( V. O. A)

BY A-A-S Criteria

TRIANGLE DON IS CONGRUENT TO TRIANGLE BOM

BY C. P. C. T

DO = BO

=> AC BISECTS BD
