Which postulate can be used to prove that the triangles are congruent?
marin [14]

<u>Answer:</u>

The correct answer option is 'not congruent'.

<u>Step-by-step explanation:</u>

We are given two right angled triangles and we to to determine if their congruence can be proved by any postulate.

Two right angled triangles are said to be congruent if the hypotenuse and one leg of a right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle.

While here, the hypotenuse of each of the triangles are not equal and neither their corresponding legs.

Therefore, these triangles are not congruent.

If r = -\sqrt{2}, and a5 = \sqrt{2}, what is the first term of the sequence?
shepuryov [24]

Answer: C

<u>Step-by-step explanation:</u>

Let x represent the first term (a₁)

a₁ = x

a₂ = x(-√2)  = -x√2

a₃ = -x√2(-√2)  = 2x

a₄ = 2x(-√2)   = -2x√2

a₅ = -2x√2(-√2)   = 4x

Since it is given the a₅ = √2, then we  can solve: 4x =√2

Divide both sides by 4 to get: x = \frac{\sqrt{2}}{4}

this can also be written as: \frac{1}{4}\sqrt{2}
