Question

In the adjoining figure, if o be the midpoint of AB and
angleOAC = angleOBD. prove that AC = BD.​

Answer 1

Step-by-step explanation:

according to SAS(side,angle,side) axioms they are equal

Answer 2

ASA(angle side angle)

Step-by-step explanation:

in ∆abc and ∆boc

angle b=angle a( each 90°)

AD=BC(given)

o(vertically opposite angle)

therefore ∆AOB=∆BOC (by ASA angle side angle)

2,.CO =OD (by CPCT)
