Analyze the diagrams. Which quadrilateral is a trapezoid? Quadrilateral M N O L is shown. Sides M L and N O are parallel and sides M N and L O are parallel. Quadrilateral M N P O is shown. Quadrilateral A B C D is shown. Sides A D and B C are parallel.

Answers

Answer:

The correct answer is - Quadrilateral A B C D is a trapezoid.

Explanation:

Quadrilateral A B C D is a trapezoid as it has exactly one pair of opposite sides that is parallel. The rest two diagrams have either more than one pair of opposite parallel lines, Quadrilateral M N O L with sides M N and L O are parallel, or none of them have a parallel line, Quadrilateral M N P O.Trapezoids are the quadrilaterals with one pair of opposite sides that is parallel.

Thus, the correct answer is - Quadrilateral A B C D is a trapezoid.

Quadrilateral A B C D is shown. Sides AD and BC are parallel is the trapezoid.

Two of the sides of a trapezoid's quadrilateral are parallel, whereas the other two are not. A trapezium is another name for it. A trapezium is a four-sided closed shape or figure that has its own perimeter and can cover a certain space. It is a 2D figurine, not a 3D one.

Every four-sided shape is a quadrilateral. Having opposite sides that are both parallel and equal in length, a parallelogram is a four-sided shape. The base multiplied by the height gives the area of a parallelogram.

Extra Credit: The 'Killer Typhoon' video presented somewhat conflicting opinions by scientists concerning the direct connection between Global Warming and 'Haiyan'. Nonetheless, they all seem to agree that global warming tend to make tropical storms more ________ if not more ____.

Answers

Answer:

Powerful.

Explanation:

Global warming tend to make tropical storms more powerful due to increase in the rate of evaporation that provides a constant source of energy transfer to the atmosphere. Increase in global temperature also increases the temperature at the equator which increases the rate of evaporation that is the main cause of producing tropical storms so that's why we can say that global warming is the main cause of producing powerful tropical storms.
