There is More The 3 4 5 Triangle has a simple beauty At its heart is a circle The circle is a Unit Circle has a radius of exactly 1 And using that circle we can cut our triangle into 6 little triangles like this Each small triangle is also a right triangle And notice that 1 2 3 1 3 4 and 2 3 5 making the 3 4 5 triangle So simple and neat What is a 3-4-5 Triangle. A 3-4-5 triangle is a special right triangle whose side lengths are in the ratio of 3: 4: 5. It is thus a right triangle with sides in the ratio of integer lengths (whole numbers) called Pythagorean triples.

3 4 5 Triangle AnglesHow do I find angles of the 3 4 5 triangle? Write down the law of cosines 5² = 3² + 4² - 2×3×4×cos (α). Rearrange it to find α, which is α = arccos (0) = 90°. You can repeat the above calculation to get the other two angles. Alternatively, as we know we have a right triangle, we have b/a = sin β and . For example a right triangle may have angles that form simple relationships such as 45 45 90 This is called an angle based right triangle A side based right triangle is one in which the lengths of the sides form ratios of whole numbers such as 3 4 5 or of other special numbers such as the golden ratio
