Question

Justify the last two steps of the proof.

Answer 1

Answer with Step-by-step explanation:

We are given that

`RS\cong UT` and
`RT\cong US`

We have to prove that
`\triangle RST\cong \triangle UTS`

We have to find the missing reason in given proof.

Proof:

Statement 1:
`RS\cong UT`

Reason: given

Statement 2:
`RT\cong US`

Reason: given

Statement 3:
`ST\cong TS`

Reason:Reflexive property

Statement 4:
`\triangle RST\cong \triangle UTS`

Reason:SSS postulate

SSS congruence property: when three sides of one triangle are congruent to corresponding sides of other triangle.Then, two triangles are congruent by SSS Postulate.

Answer 2

ST = TS is reflexive property

Note: ST and TS refer to the same segment

Triangle RST = Triangle UTS by the SSS property of congruence
you can probably just get away with saying SSS for that line.

I hope this helps.
