Any triangle with sides of 3, 4 and 5 feet will have a 90 degree angle opposite the 5 foot side If a larger triangle is needed to increase accuracy of very large structures, any multiple of 345 could be used (such as a 6810 foot triangle or a foot triangle)Answer (1 of 4) I know that I will not be answering this completely But I have some interesting information to share you with 1 Triangle with sides 3 4 5 is a Pythagorean triangle 2 An angle ought to be 90° coz it is a Pythagorean triangle 3 Angle between sides 3 and 4 is 90°, between 4 anIt will even tell you if more than 1 triangle can be created

Right Triangle General Triangle Input Results a b c General Triangle Nomenclature in counterclockwise order around triangle First side input, "S1", is always denoted asThe triangle rule states that that the length of the third side of a triangle is between the sum and difference of the lengths of the other two sidesSo, for example, if we knew that a triangle had two sides of lengths 5 and 7, respectively, then we could find the possible lengths of the third side by using the triangle rule 7 – 5 = 2Perimeter = a b c = 3 4 5 = 12 for a true 3 4 5 triangle If the triangle is scaled from the ratio by a common factor, we can multiply 12 by that common factor to get the perimeter
A triangle with side a 3, side b 4, and side c 5 units has an area of 6 square units This calculator and more easy to use calculators waiting at wwwKylesCalculatorscom Calculating theRight Triangle Calculator Please provide 2 values below to calculate the other values of a right triangle If radians are selected as the angle unit, it can take values such as pi/3, pi/4, etc Being a right triangle, the Pythagoras formula a 2 b 2 = c 2, where a = side 1, b = side 2, and c = hypotenuse is also applicable in a 345 triangle In a 345 triangle, a 2 b 2 = c 2 , here a = 3 units, b = 4 units
A 345 right triangle is a triangle whose side lengths are in the ratio of 345 In other words, a 345 triangle has the ratio of the sides in whole numbers called Pythagorean Triples This ratio can be given as Side 1 Side 2 Hypotenuse = 3n 4n 5n = 3 4 5 We can prove this by using the Pythagorean Theorem as follows ⇒ a 2 b 2 = c 2 Angle 3 and Angle C fields are NOT user modifiable Again, this right triangle calculator works when you fill in 2 fields in the triangle angles, or the triangle sides Angle C and angle 3 cannot be entered In case you need them, here are the Trig Triangle Formula Tables, the Triangle Angle Calculator is also available for angle only calculations Calculator Use This calculator solves the Pythagorean Theorem equation for sides a or b, or the hypotenuse c The hypotenuse is the side of the triangle opposite the right angle For right triangles only, enter any two values to find the third See the solution with steps using the Pythagorean Theorem formula
