Melissa's proof

1. for triangles aob and cod, angle 1 is equal to angle 2 as they are vertical angles.

2. ao = oc and bo = od because it is given that diagonals bisect each other.

3. the

_are congruent by sas postulate.

4. similarly, triangles aod and cob are congruent.

5. by cpctc, ab is equal to dc.

6. by cpctc, ad is equal to bc.

7. as the opposite sides are congruent the quadrilateral abcd is a parallelogram.

which is the missing phrase in melissa's proof?

angles adb and cbd

angles aob and cod

triangles adb and cbd

triangles aob and cod

Last one, triangles AOB and COD

Step-by-step explanation:

In step 3, they are talking about the side/angle/side postulate. That helps in describing a triangle, therefore she must be talking about a triangle

AOB and COD

Step-by-step explanation:

got the same question that was missing a different part

For triangles AOB and COD, angle 1 is equal to angle 2, as they are vertical angles.

AO = OC and BO = OD because it is given that diagonals bisect each other.

The triangles AOB and COD are congruent by SAS postulate.

Similarly, triangles AOD and COB are congruent.

By , angle ABD is equal to angle CDB and angle ADB is equal to angle CBD.

As the alternate interior angles are congruent, the opposite sides of quadrilateral ABCD are parallel.

Therefore, ABCD is a parallelogram.

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
