1st and 2nd statements are true.

Step-by-step explanation:

We are asked to choose the correct statements that can prove that quadrilateral DEFG is a parallelogram.

We will use parallelogram properties to answer this problem.

Since we know that a parallelogram has two sets of opposite angles congruent, therefore, 1st option is a correct choice.

Since a parallelogram has one set of opposite sides that are both congruent and parallel, therefore, second statement is true.

Since the consecutive angles of a parallelogram are supplementary, therefore, 3rd statement is not true.

Since the diagonals of parallelogram bisect each other, therefore, 4th statement is not true.

Answer from: smithmariah7426

a.Quadrilateral DEFG has opposite angles that are congruent then it is a parallelogram.

b.Quadrilateral DEFG has one set of opposite sides that are both congruent and parallel.Then , it is parallelogram.

Step-by-step explanation:

We have to find the statement which prove that a quadrilateral is a parallelogram.

We know that property of parallelogram

1.Opposite sides are congruent and parallel.

2.Opposite angles are congruent.

3.Sum of consecutive angles are supplementary.

4.Diagonals of parallelogram bisect to each other.

a.Quadrilateral DEFG has opposite angles that are congruent then it is a parallelogram.

It is true.

b.Quadrilateral DEFG has one set of opposite sides that are both congruent and parallel.Then , it is parallelogram.

It is true.

c.Quadrilateral DEFG has two sets of consecutive angles that are complementary .

It is false because sum of consecutive angles are supplemenatry.

d.Quadrilateral DEFG has diagonals that are congruent .

It is not true because it is not necessary but the diagonals of parallelogram bisect to each other.

Answer from: Quest

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
