Coordinate Proofs Practice SCULLY

If you want to show that segments are PARALLEL or PERPENDICULAR, you would use the _______ formula.

• Distance

• Midpoint

• Slope

If you are proving that two segments are PARALLEL, their slopes should be ________.

• equal

• different

• opposite reciprocals

• 0 and undefined

If you are proving that 2 segments are perpendicular, then their slopes will be _________.

• equal

• different

• opposite reciprocals

• both positive

If you want to show that segments (sides or diagonals) are CONGRUENT, you would use the _______ formula.

• distance

• midpoint

• slope

If you are using the distance formula to prove that sides or diagonals are congruent, then the distances should be ______.

• different

• equal

• negative

• opposite reciprocals

If you are proving that the diagonals of a parallelogram BISECT each other, you would use the ______ formula.

• slope

• distance

• midpoint

If the diagonals bisect each other, then their midpoints will be ______.

• different

• opposite reciprocals

• the same

• positive

Example 1: one slope is 3 and the other slope is -1/3

Example 2: one slope is -4/3 and the other slope is 3/4

These are two examples of slopes that are ______.

• reciprocals

• opposite reciprocals

• equal

• bisectors

If one slope is 1/2 and the other slope is -2, the sides or diagonals would be _______

• parallel

• perpendicular

• congruent

The slopes of the opposite sides of a quadrilateral both equal 3/5. This shows that the sides are _____.

• parallel

• perpendicular

• intersecting

• congruent
