Can anyone tell me what is the last condition of congruency for both the questions.

So far I’ve identified 2 each.

In both cases, you have to work on the angle between the sides you found out to be equal.

Diagram 1:

You can show that the angle PCB is the same as ACR. To prove this, you can think of angles:

and

So, angle is common, and both and are right angles.

So, angles PCB and ACR are both 90° plus a common term (ACB), and thus they're equal.

Diagram 2:

We will work very similarly here: in this case, you have

and

Again, both and are right angles, so we have

and

So, both and are 90 minus a common term, so they are equal.

step-by-step explanation: divide by 2,

no he doesnt because "-16' is negatiive
