Aug 3, 2023 · 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.

A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°.

A 3 4 5 triangle is an SSS right triangle (meaning we know the three side lengths). If we know two of the side lengths and they are congruent with the 3 4 5 ratio, we can easily determine the third side length by using the ratio.

Make a 3,4,5 Triangle ! Connect three lines: 3 long; 4 long; 5 long; And you will have a right angle (90°)

The 3:4:5 triangle is useful when you want to determine if an angle is a right angle. For example, suppose you have a piece of carpet and wish to determine if one corner of it is 90°. First measure along one edge 3 feet.

Aug 5, 2024 · A 3-4-5 triangle is a type of right-angled triangle where the lengths of the sides follow the ratio 3:4:5. This means that if one side of the triangle is 3 units long, the next side is 4 units long, and the hypotenuse (the side opposite the right angle) is 5 units long.

Feb 24, 2025 · The triangle with edge lengths 3, 4, and 5 is the right triangle with smallest possible integer lengths and corresponds to the Pythagorean triple (3,4,5) where the legs have lengths 3 and 4 and the hypotenuse length 5. It satisfies the Pythagorean theorem since 3^2+4^2=5^2. (1) It has inradius r=1.

3 4 5 - Right scalene Pythagorean triangle, area=6. Computed angles, perimeter, medians, heights, centroid, inradius and other properties of this triangle.

The 3-4-5 right triangles are special right triangles that exhibit a unique Pythagorean triple for their side lengths ratio. Knowing what makes these triangles special will simplify the process of solving right triangles’ measures and word problems involving these triangles.

The 3-4-5 triangle method provides a way to check and create other right triangles using proportional side lengths to the constant ratio 3:4:5. The proportions will create similar triangles.
