If angles and lengths are involved in the problem, we may also need to use trigonometry. If the base of the prism has dimensions x and y, and the diagonal along the base is represented by c, then x + y = c. The longest diagonal in the solid, s, is the hypotenuse of the triangle formed by the sides c and the height of the solid, z. Here, we observe the distance from the centre to C is half the distance from A to C. Given that we know the width of the square-based triangle, we can find the length of AC, halve it, and then use the result as a part of Pythagoras theorem to find the perpendicular height. We also provide a separate answer book to make checking your answers easier! Now we know FH, our first triangle, FCH, looks like this: Now, we know two side-lengths of this triangle, we can use Pythagoras theorem to find the third, FC, which is the answer to the whole question.

The length MX is 26.5 cm (to 1 decimal place). To find side-length FH, we need to use trigonometry, \cos(26) = \dfrac{\text{Adjacent}}{\text{Hypotenuse}} = \dfrac{9}{FH}. We can see that the side we have labeled x forms the diagonal line of the base of the cuboid. 8rC??YPufWyWs\wG/0aIXo [j Ydin^)$o@VXo7`s3A9weO("QXq*MByAQ>XEfcrB%$(0ty%`~SatZ&}O'#Ct#e(W,0r*Jm4D-cMT 3ILgF $A!;X'nD8RvHYJ2P Corbett Maths offers outstanding, original corbettmaths 3d pythagoras textbook.
