Free online calculator, basic and scientific computing

Logarithm calculator online math calculator.The two sides of such a triangle are equal, and the hypotenuse is immediately calculated by the equation c = a√2. If the hypotenuse value is given, the side length will be equal to a = c√2/2. Triangle - set square Triangle (set square). The red one is a 45 45 90 degree angle triangle 45 45 90 Triangle Rules and Properties The most important rule is that this triangle has a right angle and the other two angles are equal to 45°. This means that the two sides - the legs - are of equal length and the hypotenuse can be easily calculated. Other interesting properties 45 45 Among the 90 triangles are: This is the only possible right triangle that is also an isosceles triangle The ratio of the hypotenuse to the sum of the legs is the smallest The ratio of the height of its hypotenuse to the total height of the legs is the largest 45 45 90 Triangle ratio 45 45 90 Triangles - Tiles In a 45 45 90 triangle, the ratio is equal to: 1 : 1 : 2 for angle (45° : 45° : 90°) 1 : 1 : √2 side (a : a : a√2) How to solve a 45 45 90 triangle: an example Check out this real life example to understand the 45 45 90 triangle rule. Suppose we want to solve isosceles triangles from a set of triangles. Enter the given value. In our case, the easiest way is to use the scale to enter the length of the part. The usual leg length is 9 inches, so enter this value into the a or b box. 45 45 90 The trigonometric calculator shows the remaining parameters. Now you know: Length of hypotenuse - 9 in * √2 = 12.73 in Area - 9 inches * 9 inches / 2 = 40.5 inches² Circumference - 9 inches + 9 inches + 9 inches * √2 = 30.73 inches Remember, you can change the displayed unit every time you just click on the unit name. Also, don't forget that our calculator is a flexible tool - it also works if you only know the area, hypotenuse, or even perimeter The remaining parameters can be calculated. Awesome!
