Understanding Quadrilaterals

What is the first step in solving the problem of plotting ordered pairs to form a quadrilateral?

• Calculate the area of the quadrilateral

• Plot the points and label them

• Identify the type of quadrilateral

• Find the perimeter of the quadrilateral

Which property is essential to prove that a quadrilateral is a rectangle?

• All sides are equal

• Opposite sides are parallel

• Diagonals are congruent

• All angles are right angles

How can you prove that two lines are perpendicular?

• By showing they intersect at a point

• By showing their slopes are negative reciprocals

• By showing they have the same slope

• By showing they are parallel

What conclusion was reached about the quadrilateral after calculating the slopes?

• It is a rhombus

• It is not a rectangle

• It is a rectangle

• It is a square

What characteristic of a parallelogram was used to identify the quadrilateral?

• Diagonals bisect each other

• All sides are equal

• Opposite sides are parallel

• All angles are equal

Which formula is used to find the length of the sides of the quadrilateral?

• Perimeter formula

• Slope formula

• Area formula

• Distance formula

What was the final classification of the quadrilateral?

• Rhombus

• Parallelogram

• Square

• Rectangle

Why was the quadrilateral not classified as a rectangle?

• It did not have right angles

• It had equal sides

• It had congruent diagonals

• It had parallel sides

What mathematical evidence supports the classification of the quadrilateral as a parallelogram?

• Diagonals are congruent

• All sides are equal

• All angles are right angles

• Opposite sides are parallel

What was the initial assumption about the quadrilateral before calculations?

• It was a rhombus

• It was a rectangle

• It was a square

• It was a trapezoid
