Question

1. In the quadrilateral ABCD,
AC = AD and AB bisect ZA
and AABC SAABD. The
relation between BC and BD is

O BC > BD
O BC = BD
O BC < BD
O none of these
​

Answer 1

Answer:

In △ABC and △ABD,

AC=AD (Given)

∠CAB=∠DAB (AB bisects ∠A)

AB=AB (Common)

∴△ABC≅△ABD (By SAS congruence rule)

∴BC=BD (By CPCT)

∴, BC and BD are of equal lengths.
