It’s 90º, there are two operative theorems.

of the two sides of the squares of the two sides of the hypotenuse. (For sides of different lengths to 3: 4: 5) 3 & 4 are adjacent sides and 5 the hypotenuse. 3² + 4² = 5²

this is the right angle for the triangle is always formed.

In feet or meters Multiples of 1 Ratios 3: 4: 5 Formula 3² + 4² = 5² Multiples of 2 Ratios 6: 8: 10 Formula 6² + 8² = 10² Multiples of 3 Ratios 9:12:15 Formula 9² + 12² = 15² Multiples of 4 Ratios 12:16:20 Formula 12² + 16² = 20² < Span> Multiples of 5 Ratios 15:20:25 Formula 15² + 20² = 25² Multiples of 6 Ratios 18:24:30 Formula 18² + 24² = 30² Multiples of 7 Ratios 21:28:35 Formula 21² + 28² = 35² Multiples of 8 Ratios 24:32:40 Formula 24² + 32² = 40² And so on To apply the formula, hammer a sharpened peg 2 ???? x2 ???? in one corner then a hammer in the center. This will be peg A Using a 100 ?? 0 ???? The tape is a hook. Leave it on the ground. 0 ???? mark, hammer another peg as in 1, above. This will be a peg. It’s 90 ° to the baseline, on the ground.
