The proof shows that opposite angles of a parallelogram are congruent. Given: ABCD is a parallelogram with diagonal AC. Prove: ∠

Rom4ik [11]

A parallelogram is a figure which has its opposite sides to be equal and parallel. The missing reason in the proof is:

B. Substitution Angle Angle Postulate.

A parallelogram is a type of quadrilateral that has its opposite sides to be equal and parallel. The sum of its internal angles is $360^{o}$ .

To prove that ∠ BAD ≅ ∠ DCB, we have:

Given parallelogram ABCD;

<BAC ≅ <ACD (alternate angle theorem)

<DAC ≅ <ACB (alternate angle theorem)

<BAC + <DAC = <BAD

Also,

<BCA + <DCA = <BCD

Therefore,

<BAD ≅ <DCB (Substitution Angle Angle Postulate)

Thus, the missing reason in the partial proof is:

option B. Substitution Angle Angle Postulate

A sketch is attached to this question for more clarifications.

PLS HELP!! AND HURRY!! Find an expression for the nth term ( tn ) in each of the following sequences:

fiasKO [112]

If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule

$\begin{cases}a_1=1\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}$

From this definition, we can write $a_n$ in terms of $a_1$ :

$a_2=a_1+3$

$a_3=a_2+3=(a_1+3)+3=a_1+2\cdot3$

$a_4=a_3+3=(a_1+2\cdot3)+3=a_1+3\cdot3$

$a_5=a_4+3=(a_1+3\cdot3)+3=a_1+4\cdot3$

and so on, up to

$a_n=a_1+(n-1)\cdot3$

(notice how the subscript on a and coefficient on 3 add up to n)

$a_n=1+3(n-1)=3n-2$
