What is the length of the diagonals of trapezoid
Possible Answers:
Correct answer:
Explanation:
To find the length of the diagonal, we need to use the Pythagorean Theorem. Therefore, we need to sketch the following triangle within trapezoid
We know that the base of the triangle has length
Dividing by two, we have the length of each additional side on the bottom of the trapezoid:
Adding these two values together, we get
The formula for the length of diagonal
Plugging in our values, we get:
Find the length of both diagonals of this quadrilateral.
Possible Answers:
Correct answer:
Explanation:
All of the lengths with one mark have length 5, and all of the side lengths with two marks have length 4. With this knowledge, we can add side lengths together to find that one diagonal is the hypotenuse to this right triangle:
Using Pythagorean Theorem gives:
Similarly, the other diagonal can be found with this right triangle:
Once again using Pythagorean Theorem gives an answer of
Find the length of the diagonals of this isosceles trapezoid, with
Possible Answers:
Correct answer:
Explanation:
To find the length of the diagonals, split the top side into 3 sections as shown below:
The two congruent sections plus 8 adds to 14.
We can solve for the diagonal, now pictured, using Pythagorean Theorem:
Find the length of the diagonal of the isosceles trapezoid given below.
Possible Answers:
Correct answer:
Explanation:
In order to calculate the length of the diagonal, we first must assume that the height is perpendicular to both the top and bottom of the trapezoid.
Knowing this, we can draw in the diagonal as shown below and use the Pythagorean Theorem to solve for the diagonal.
We now take the square root of both sides:
