Question

PLEASE HELP ME ANSWER super desperate! will MARK BRAINLIEST

Answer 1

Answer:

Line QR = line BC

Step-by-step explanation:

To prove congruency using the SAS theorem, (SAS = Side Angle Side)

You obviously need 2 sides and 1 angle.

BUT

The ONE angle has to be right between the TWO sides, hence the name: side ANGLE side.

So coming to your problem:

We know angle Q = angle B. And QS=BD

We need one more SIDE. Pick side QR in triangle RQS. Is angle Q in the middle of QR and QS?

Yes it is!

Now find the corresponding side in the other triangle to QR. This is the shortest side, BC.

Check:

Is angle B in the middle of CB and BD?

Yes!!

So you can prove the congruency of these two triangle using the SAS theorem if you know that BC = QR. That’s your answer.

Hope this helped!!!!!

PS let me know if it’s correct!
