Choose the congruence theorem that you would use to prove the triangles congruent. sss sas asa aas

- AAS congruence theorem.

Explanation:-

In the given question , there is only one theorem i.e. AAS theorem and all the remaining options (SSS ,SAS , ASA ) are postulate not theorem.

Therefore, AAS congruence theorem is the right answer.(as in the given picture both triangles have two equal angles and one side )

The AAS (angle-angle-side) theorem states that if two angles and any side of one triangle are equal to two angles and any side of another triangle, then the triangles are congruent.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
