#### Answer:

By reading.

#### Explanation:

The way you interpret the problem is the start, let me give you an example:

Triangle "1" Has 3 sides,

Using Pythagoras' Theorem, we know

#A^2 = 9# ,#B^2 = 16 implies A^2 + B^2 = 9 + 16 = 25#

SInce

#C = sqrt(C^2) = sqrt(25) = 5#

You simply find out what value goes with what part of the formula, and do this for each, and then work out the formula as normal.
