Question

justify the last two steps of proof

symmetric property of =; SSS
reflexive property of = SAS
reflexive property of=;, SSS
symmetric property of = SAS

Answer 1

4.SSS because of one side is common and two sides are equal.

Answer 2

Answer: reflexive property , SSS postulate

Step-by-step explanation:

In the given picture we can see that In Δ RST and ΔUTS

RS=UT [given]

RT=US  [given]

ST=TS  [Reflexive property]

⇒Δ RST ≅ ΔUTS  [BY SSS congruence postulate]

• SSS congruence postulate says that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
