5. Justify the last two steps of the proof. Given: RS = UT and RT = US

Prove: RST = UTS

proof | given

1. RS = UT | 1. Given

2. RT = US | 2. Given

3. ST = TS | 3.

4. RST = UTS | 4.

From the question it is given in a ΔRST and Δ UTS  

RS = UT

RT = US

proof:

RS = UT    {given}

RT = US    {given}

ST = TS     {Common}

Therefore, by SSS theorem ΔRST and Δ UTS  is congurent

RST = UTS    {SSS Theeorem}
