Monomials are the expressions with one terms.

A.) $-4+6 = 2$

Since, it has only one term. Therefore, it is a monomial.

B.) $b+2b+2 = 3b+2$

Since, it has two terms. Therefore, it is not a monomial.

C.) $(x-2x)^2 = (-x)^2=x^2$

Since, it has only one term. Therefore, it is a monomial.

D.) $\frac{rs}{2}$

Since, it has only one term. Therefore, it is a monomial.

E.) $36x^2yz^3$

Since, it has only one term. Therefore, it is a monomial.

F.) $a^x$

Since, the variable is in the power. So it is not a monomial.

G.) $x^\frac{1}{3}$

Since, the power is not a integer. Therefore, it is not a monomial.

You have to prove that 2 angles are conguent to the other triangles angles; example: ∠A≅∠C by the additon POC (2 of those) and then one side; example: AB≅BA by the reflexive POE (1 of those)

I cant see the triangles but thats how you do them, also im learning this right now too, look up the triangle congruence things like ASA ≅ SSS≅ HL≅ exc. a chart will explain how to prove them using that:
