B.) Same shape

D.) Similar

In the given picture we have two triangles, ΔQRS and ΔTUV

such that ∠Q=∠T=56°

∠R=∠U=83°

∠S=∠V=41°

So by AAA postulate of similarity, we have

ΔQRS ≈ ΔTUV

 Since, similar figure have same shape.

Thus, we can say both triangles have the same shape.

But non of sides of both triangles are congruent, therefore the given triangle is just similar but not congruent.

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
