EF is a median of trapezoid ABCD. If the length of EF is 14x and the length of CD is 20x what is the length of AB in terms of x?

8x


Ef is a median of isosceles trapezoid abcd find ef if ab is equal to 14 inches what is the length of ccd in terms of x?

It is not possible to answer the question because there is insufficient information. Also, there is no way of telling whether the trapezoid has AB parallel to DC (with AD and BC equal) or if AD is parallel to CB (with AB and DC equal). It is not clear what is meant by ccd. What is x? In any case, the length of one side, whichever it is, is not enough to answer the question.


If EF is a median of isoceles trapeziod ABCD. The length of AB is 12 and the length of CD is 18. the length of BF is 5. What is the length of DE?

The length of DE is 5.


Prove that the line which divides the nonparallel sides of a trapezium proportionally is parallel to the third side.?

To prove that the line which divides the nonparallel sides of a trapezium proportionally is parallel to the third side, we can use the property of similar triangles. Let the trapezium ABCD have sides AB and CD as the nonparallel sides, and side BC as the third side. Let the line dividing AB and CD be denoted as EF, with E on AB and F on CD. By the property of similar triangles, we can show that triangles AEF and BCF are similar, and hence their corresponding angles are congruent. This proves that EF is parallel to BC.


(h plus j) - ef?

The numerical value will depend on the values of each variable. The expression can't be further simplified, except that the parentheses can be omitted.
