We also need to find out the height of the rifles or, in other words, the length of the side sides of the triangle and, accordingly, trapezoid. To do this, we will use the Pythagorean theorem. The height of our isosceles triangle divides it into 2 rectangular. Thus, we know the length of two legs — 5 and 5 m (half of the length of the isosceles triangle). Following the theorem, we build each side in a square, fold the obtained values and calculate the square root from this number. In this case, it will be approximately 7.1 m — this is what will be the length of the tac rafters. Based on this size and knowing the step to the central intermediate rafter, you can find out its length, using the same Pythagorean theorem. The length of the rest of the rafters can be calculated according to special tables available on the Internet.
