04.01 Using the Coordinates

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent?

A. Use the slope formula to prove the slopes of the opposite sides are the same.
B. Use the slope formula to prove the slopes of the opposite sides are opposite reciprocals.
C. Use the distance formula to prove the lengths of the opposite sides are the same.
D. Use the distance formula to prove the midpoints of the opposite sides are the same.

answer: h

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: 4 (:
