Question

In the figure, ABCD aid a quadrilateral in which AB= AD and BC = DC. Diagonals AC and BD intersect each other at O. Show that -
(i) ABC ≈ ADC
(ii) AOB ≈ AOD
(iii) AC is linear to BD
(iv) AC bisects BD

Answer 1

Answer:

because they are equally opposite to each other

Answer 2

according to the figure that ,

given, AB=AD and BC=DC and AC and BD intersects each other at 0.

Step-by-step explanation:

1st ly, according to ABC and ADC

AB=AD (equal line)

BC=DC (equal line)

and AC=AC (common line)

so prove that than ABC = ADC

2ND ly , according to AOB and AOD

AB=AD (equal line )

BO=DO (equal line )

and AO= AO (common line)

so prove that than AOB = AOD
