Answer:

Solution given:

(x_1,y_1)=(1,2)

(x_2,y_2)=(10,10)

now

slope [m]=\frac{y_2-y_1}{x_2-x_1}=\frac{10-2}{10-1}=\frac{8}{9}

5. Justify the last two steps of the proof.
elixir [45]

Answer:

ST & TS are congruent

RST and UTS are congruent

Step-by-step explanation:

The question is not properly presented; however, I've added an attachment to give a clear picture of the question.

Required

State the property that justifies:

ST = TS

Triangles RST = UTS

From the question, we have that:

RS = UT

RT = US

In plane geometry, the length of ST is still the same as the length of TS.

This implies that:

ST = TS because ST is congruent to TS

Moving further to determine the relationship between triangles RST\ \&\ UTS

Comparing both triangles:

They have a similar side ST and TS because ST = TS

And we also have that: RS = UT

So, we can conclude that: RST = UTS because they are congruent
