Parallelograms in the Coordinate Plane

Drew used the distance formula and found each side to have a distance of 4. What does that mean?

• Side AB and AD are parallel

• Side AB and AD form a right angle

• Side AB and AD are congruent

• Nothing Specific

The slope of side AB is -3 and the slope of DC is -3. What does this mean?

• Side AB and AD are parallel

• Side AB and AD form a right angle

• Side AB and AD are congruent

• Nothing Specific

Julia proved ETNU is a parallelogram. She notices that side ET has a slope of 1/2 and EN has a slope of -2. What does this mean?

• Side ET and EN are parallel

• Side ET and EN form a right angle

• Side ET and EN are congruent

• Nothing Specific

Julia proved ETNU is a parallelogram. She notices that side ET has a slope of 1/2 and EN has a slope of -2. What can she classify ETNU as?

• A rectangle

• A square

• A rhombus

• Just a parallelogram

Use the distance formula to see if side BC is congruent to side AD.

• Yes they are congruent

• No, they are not congruent

In the image, side AB has a slope of -3 and AD has a slope of 1/3. What does this mean is true?

• Side AB and AD are parallel

• Side AB and AD form a right angle

• Side AB and AD are congruent

• Nothing Specific

XWYZ looks like it is a square, but what two slopes here prove it has right angles?

• 0 and undefined

• -1 and 1

• -1/2 and 1/2

If you think this shape is specifically a rhombus, which of the following could prove it?

• All sides are congruent

• Opposite sides are parallel

• Diagonals are congruent

• Diagonals bisect each other

• Diagonals are perpendicular

Parallelogram RSTU is rotated 180º clockwise about vertex R. How many pairs of parallel sides does the rotated figure have?

• 1

• 2

• 3

• 4

Write the words in the blank space that correctly complete the sentence. Since the preimage can / cannot be mapped onto the image by a sequence of transformations, the parallelograms are / are not congruent.
