Question

if figure 1 , AC and BC bisect each other at o. prove that triangle AOB
congruence triangle COD
​

Answer 1

Answer:

Step-by-step explanation:

In triangles AOB and COD, we have

          ∠A=∠C           [Given]

and,    ∠1=∠2            [Vertically opposite angles]

Therefore, by AA-criterion of similarity, we have

          △AOB∼△COD                      [Hence proved]
