Question

in the given figure ABC is right angled at B and BD is drawn perpendicular to AC. show that 1=2 ​

Answer 1

Answer:

in triangle ABC and CDB,

angle A is common to both(SAY X),

angle ABC = angle ADB=90°

therefore angle ABD (1)= angle DCB(2) =180-90-x

=90-x

Hence angle ABD (1)= angle DCB(2)
