Prove that the diagonals of a parallelogram bisect each other​
Nady [450]

Answer:

[ See the attached picture ]

The diagonals of a parallelogram bisect each other.

✧ Given : ABCD is a parallelogram. Diagonals AC and BD intersect at O.

✺ To prove : AC and BD bisect each other at O , i.e AO = OC and BO = OD.

Proof :\begin{array}{ |c| c |  c |  } \hline \tt{SN}& \tt{STATEMENTS} & \tt{REASONS}\\ \hline 1& \sf{In  \: \triangle ^{s}  \:AOB \: and \: COD  } \\  \sf{(i)}&  \sf{ \angle \: OAB =  \angle \: OCD\: (A)}& \sf{AB \parallel \: DC \: and \: alternate \: angles} \\  \sf{(ii)} &\sf{AB = DC(S)}& \sf{Opposite \: sides \: of \: a \: parallelogram} \\  \sf{(iii)} &\sf{ \angle \: OBA=  \angle \: ODC(A)} &\sf{AB \parallel \:DC \: and \: alternate \: angles} \\  \sf{(iv)}& \sf{ \triangle \:AOB\cong \triangle \: COD}& \sf{A.S.A \: axiom}\\ \hline 2.& \sf{AO = OC \: and \: BO = OD}& \sf{Corresponding \: sides \: of \: congruent \: triangle}\\ \hline 3.& \sf{AC \: and \: BD \: bisect \: each \: other \: at \: O}& \sf{From \: statement \: (2)}\\ \\ \hline\end{array}.

Give brainlest on time limit pls help
inysia [295]

Answer:

336 sq un

Step-by-step explanation:

The area of a rhombus is pq/2 where p and q are the diagonals.

you have:

p = 12 + 12 = 24

q = 18 + 10 = 28

so the formula would be:

24 * 28 / 2 = 336 sq un

Given line l and line M are parallel. Find the value of x and y.
Liula [17]

Answer:

x = 4

y = 10

Step-by-step explanation:

29x - 3 + 15x + 7 = 180 (Linear Pair)

44x + 4 = 180

44x + 4 = 180 - 4

44x = 176

\frac{44x}{44} = \frac{176}{44}

x = 4

29(4) - 3

116 - 3

113

13y - 17 = 113 (Alternate Exterior Angles Theorem)

13y - 17 + 17= 113 + 17

13y = 130

\frac{13y}{13} = \frac{130}{13}

y = 10
