Given ad cb adb cbd prove: ∆adb ≅ ∆cbd

look at the proof. name the postulate you would use to prove the two triangles are congruent.

Step-by-step explanation:

Notice that sides AD and BC are congruent, also DB is a common side to both triangles. At this point, we already have two corresponding congruent sides.

Additonally, angles ADB and CBD are congruent. In summary, we have two pair of corresponding sides congruent, and one pair of corresponding angles congruent (which is formed by the congruent sides).

Based on all the given information, by SAS postulate triangles ADB and CBD are congruent.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
