Which statements are true about the parallelograms? select three options.

These are the properties of a parallelogram

•Opposite angles are equal

•The sum of all the angles is equal to 360 degrees

•Opposite angles are equal

•When the diagonals of a parallelogram are drawn, they bisect each other

•When a diagonal is drawn to separate the parallelogram into two, the two separate sides are equal when compared

•The sum of two adjacent angles in parallelogram is equal to 180 degrees

Step-by-step explanation:

For example,

Opposite angles (A and  D) and (B and C) are equal

The sum of all the angles give 360 degrees,  angles A + B + C + D = 360

Side AB is equal to side CD  (/AB/ = /CD/)

The sum of adjacent angles A and C gives 180  [angles (A + C ) = 180]

Choose the option similar to any of these properties in the question

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
