Question

In quadrilateral ACBD, AC = AD and AB bisects
Show that triangleABC congruent triangleABD.

What can you say about BC and BD?
​

Answer 1

Answer:

helo guys its your answer

Step-by-step explanation:

To prove :Triangle ABD congruent to triangle BCD. Therefore both the Triangles are congruent by SAS(side angle side) congruency. Hence proved

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)
