"The diagonals of a trapezoid are perpendicular and have lengths 8 and 10. Find the length of the median of the trapezoid."

I don't think this is determined. Take a look at

and you can see that depending on how you divide the diagonals, the median can be a variety of lengths.

To find the length of the median of the trapezoid, we can use the fact that the diagonals of a trapezoid bisect each other. Let's use this information to determine the length of the missing side of the trapezoid.

Step 1: Draw the trapezoid and label the given information. Let's call the trapezoid ABCD, where AD is the longer base, BC is the shorter base, and E is the intersection point of the diagonals.

Step 2: Draw the diagonals AC and BD, and label their lengths. Given that AC = 8 and BD = 10, let's label these lengths on our diagram.

Step 3: Use the fact that the diagonals bisect each other. This means that the line segments AE, EC, BE, and ED are equal in length.

Step 4: Now, let's focus on the length of the median. The median of a trapezoid is the line segment connecting the midpoints of the two bases. Let's label the midpoint of AB as F and the midpoint of CD as G.

Step 5: Connect points F and G to form the median line FG.

Step 6: Since FG is a straight line, it is also divided into equal segments by the intersection point of the diagonals E. Therefore, FG can be divided into EF, FG, and EG.

Step 7: Since EF and EG are halves of AE and EC, respectively, we can label them as EF = AE/2 and EG = EC/2.

Step 8: Finally, to find the length of the median FG, we need to add EF and EG. Substitute the values from step 7 into the equation: FG = EF + EG = AE/2 + EC/2.

Step 9: Now substitute the lengths of the given diagonals into the equation. FG = (AC/2) + (BD/2).

Step 10: Calculate the values. FG = (8/2) + (10/2) = 4 + 5 = 9.

Therefore, the length of the median of the trapezoid is 9 units.
