State if the triangles in each pair are similar. If so, state how you know they are similar and complete the similarity statement. QRS ~ _

a. similar, SAS, QLK
b. similar, AA, LQK
c. not similar
d. similar, SSS, LQK​

Let me steal some point real quick. I don't think you mind me having this small point. Do you ?

I hope someone else can help you with your question.  

Fun fact:  2 people can answer your question

I hope no one will answer any spam links.

Good luck.

In ΔQRS and ΔQLK,

QR/QL = QS/QK

28/4 = 28/4

7/1 = 7/1 --[1]

AngleLQK and AngleRQS are equal (VOA)

Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.

[A] ΔQRS ~ ΔQLK by SAS similarity.

. similar, AAA QLK

Step-by-step explanation:

<K=<L base angle of isosceles triangle

<R=<S base angle of isosceles triangle

<KQL=<RQS vertically opposite angle

so

<K=<L=<R=<S

so

∆QRS~QLK by AAA axiom

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

may i see the picture? it would a lot, xox
