Determine if the triangles, ΔYPQ and ΔNPD, are similar. If so, identify the similarity criterion.
A) AA similarity
B) SAS similarity
C) SSS similarity
D) not similar

The answer to your question is A) they are similar because of AA criterion

Step-by-step explanation:

- ∠ QYP is ≅ to ∠ DNP           given

- ∠ QPN is ≅ to ∠ DPN           vertical angles

- ∠ YQP is ≅ to ∠ NDP            if two angles are congruent third angle

                                                is also congruent.

Conclusion

ΔYPQ is similar to ΔNPD because of AA similarity.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
