What else would need to be congruent to show that abc def by aas (apex)

B.  

Step-by-step explanation:

The AAS theorem says that if two angles and any side of a triangle are equal to two angles and any side of another triangle then the triangles are congruent.

In the given picture, we have two triangles having one side and one angle equal .

To prove the given triangles congruent by AAS theorem we need one more pair of angles congruent .

We can take option A.

but then the triangles wuill become conruent by ASA postulate not AAS.

Therefore, we need   to prove the given triangles congruent by AAS theorem.

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
