Given the length of three sides of a triangle, which is a right triangle?
RSB [31]

The aides of a right triangle will always satisfy the Pythagorean relationship ...

                   a² + b²=  c²

We can take each of these and try it out:

(1) ... 10² + 24² = 100 + 576  = 676
         √676 = <em>26  Yes</em>.

(2) ... 12² + 18²  =  144 + 324  =  468
           √468  =  21.6, not 20.  <em>No.</em>

(3) ... 15² + 26²  =  225 + 676  =  901
         √901  =  30.017  Awfully close.  As an engineer, I'll buy this one. <em>Yes.</em>

(4) ...  40² + 50²  =  1,600 + 2,500  =  4,100
          √4,100  =  64.03, not 80.<em>  No.</em>

How do I find the lateral and total surface area of the prism.
Roman55 [17]
<h3>Explanation:</h3>

<em>Lateral Area</em>

The lateral area is the area of the sides of the prism. If the faces are perpendicular to the bases, then each face is a rectangle. The area of each rectangle is the product of its length and width, generally the product of the height of the prism and the length of one edge of the base.

The total lateral area will then be the product of the height of the prism and the perimeter of the base.

<em>Total Area</em>

The total area is the sum of the lateral area (computed as above) and the area of the two bases of the prism. The formula for that area depends on the shape of the prism. (You have already seen formulas for the areas of triangles, rectangles, and other plane shapes. If not, they are readily available in your text or using a web search.)
