" please give me a link to an/or explanation of why that is so. This triangle calculator calculates the sides, angles, perimeter and area of any triangle no matter of its type (right, isosceles, equilateral) based on the. And I want to know how to prove things so if you want to tell me something like "this is always true for. I bet there's a better way that I'm not seeing. And then the base would be just $\sin/2$Īnyway, that was just an example to try to explain how I was thinking when I set the equation up. Visually what I did was thinking of the triangle's height being the x-coordinate from $x = 1$, so with an angle of $2\pi/3$ I get height = 1½ for example. functions).Īnyway, was I doing the right thing but I may have messed up with the formulas or is there something I could do instead? What I got though is a mess of trigonometric stuff that I found impossible to solve (my memory is bad so I easily forget formulas for trig. Sides: a 13 b 13 c 10 Area: T 60 Perimeter: p 36 Semiperimeter: s 18. The angle 14.5° and leg b 2.586 ft are displayed as well. Ladder length, our right triangle hypotenuse, appears Its equal to 10.33 ft. an equilateral triangle base, and 3 identical isosceles triangle sides. Enter the given values.Our leg a is 10 ft long, and the angle between the ladder and the ground equals 75.5°. When I tried to solve it I thought that I could do it like I would do with a square:įind an equation f(x) = 2*(sqrt((1 - cos x)² + sin² x) + sin x) => perimeterĪnd find what angle would satisfy those conditions. Calculation of the isosceles triangle c10 a13 - Triangle calculator. Volume of Polygonal Pyramids using Side length or Perimeter Level 2 The side. What I'd like to ask is what is the best way of solving this, if you don't assume this? I was given this problem on an exam and I usually sit down and do them just because I like solving these kinds of problems but I couldn't get it to work because I got too many messy equations and I had no time to clean up. I wanted to ask how to actually prove that or something. So I have seen this question asked before but with variations (circle of radius 4, and an equilateral triangle) and so I am hoping for an answer on how to do this.Īfter looking around I saw that people assume that the maximum perimeter of such a triangle is equilateral, meaning you have all the degrees.
