Use trigonometry
The slant height is the hypotenuse of the right triangle formed by the height of the cone and the radius of the base. Use the Pythagorean theorem. The Pythagorean theorem (radius)2 + (perp. height)2 = (slant height)2
They can measure height and length from a distance using Pythagoras' theorem
If it is a right triangle, use the Pythagorean theorem. If it is iscossolese or scalene, draw line down middle, use pythagorean theorem to solve for missing side.
if you know the height and the apothem, use pythagorean theorem to solve for it.
the Pythagorean theorem helps find the value of the longest side in a right triangle if you know the value of the base and the height.
In a right angle triangle the square of the hypotenuse is equal to height squared plus base squared
Use the Pythagorean theorem (a-squared + b-squared = c-squared) Remember, the hypotenuse is c.
If the prism is a rectangular parallelepiped (that is, all the angles are right angles), just add the squares of the 3 dimensions (length, width, and height) together, and take the square root. This involves 2 applications of the Pythagorean Theorem.
The "slant height" is called the lateral height.There is no formula. However, if you find the radius of the base and the height of the cone, you can form a triangle. Now use the Pythagorean theorem. Radius2 + height2 = lateral height2.
Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.
Since the triangle has a hypotenuse, it must be a right triangle. Therefore, the Pythagorean theorem applies, and the height of the triangle must be sq rt (32 - 22).
Pythagorean theorem a2 + b2 = c2 You have to know at least two of the sides See the below link http://en.wikipedia.org/wiki/Pythagorean_theorem
