Question

in a quadrilateral ACBD AC BD and AB biscuits LA show that ∆ABC= ∆ABD​

Answer 1

Answer:

by SAS congruence rule

∆ABC congruent ∆ABD

AC = AD

ANGLE BAC =ANGLE BAD ..........SINCE IT BISECTS

AB = AB ........COMMON SIDE

Answer 2

Question :-

In quadrilateral ACBD, AC = AD and AB bisects ∠ A (see figure). Show that ∆ABC ≅ ∆ABD. What can you say about BC and BD?

Answer :-

In quadrilateral ACBD, we have AC = AD and AB being the bisector of ∠A.

Now, In ∆ABC and ∆ABD,

AC = AD (Given)

∠ CAB = ∠ DAB ( AB bisects ∠ CAB)

and AB = AB (Common)

∴ ∆ ABC ≅ ∆ABD (By SAS congruence axiom)

∴ BC = BD (By CPCT)
