Question

Can someone please help?!
Justify the last two steps of the proof.
attachment below.

Answer 1

Reason 3. There is aproperty of equality and congruence that something is equal to itself, and something is congruent to itself. It's the Reflexive Property.

Answer 2

Reason 4. Look at statements 1-3. What parts of one triangle have been proved congruent to corresponding parts of the other triangle?

Answer 3

All of them have been proved to be congruent of each other

Answer 4

Yes, but what are they? Sides of the triangles, angles of the triangles, or some side s and some angles? What ere those three pairs of congruent things in steps 1-3?

Answer 5

the sides

Answer 6

This is what i have as an answer but I know im missing one but not sure where. The congruent corresponding parts are angles; PQ<TS, QR<SR, PR<TR.

Answer 7

It says I need 3 pairs of corresponding sides and corresponding angles. idk what they are.

Answer 8

@mathstudent55 ?

Answer 9

Yes, the sides. You are right. Since you proved all three sides of one triangle congruent to the three sides of another triangle, you used SSS. So reason 4. is SSS

Answer 10

The two reasons are:
3. Reflexive property
4. SSS

Answer 11

Thank you!!
