Tommy is writing a coordinate proof to show that the midsegment of a trapezoid is parallel to its bases. he starts by assigning coordinates as given, where rs¯¯¯¯¯ is the midsegment of trapezoid klmn .

The midsegment RS divides sides KN and LM into equal halves.

The coordinate of S is (a + d, c) and the slope of RS is 0

The coordinate of S is calculated using the following midpoint formula:

So, we have:

Add 2c and 0

Divide both fractions

RS is parallel to KL.

So, the slope of RS is 0

Hence, the coordinate of S is (a + d, c) and the slope of RS is 0
