Our website provided core java programs examples with output aid beginners and expert coders to ("Area of Isosceles triangle = " + a ) Įnter the length of base(unequal side) = 3 ("Enter the length of base(unequal side) = " ) So, let’s see the program to understand it more clearly. In this approach the length of equal sides of isosceles triangle and the length of base will be taken as input from the user, which will be used to calculate the area based on the area calculation formula. Return (float)(Math.sqrt(Math.pow(s1, 2) - (Math.pow(s2, 2) / 4))) Īrea of Isosceles triangle = 1.9843135 Method-2: Java Program to Find Area of Isosceles Triangle By Using User Input Value
Static float altitude(float s1, float s2) In this approach the length of equal sides of isosceles triangle and the length of base is already declared in the program, which will be used to calculate the area based on the area calculation formula. Method-1: Java Program to Find Area of Isosceles Triangle By Using Static Value The best and excellent way to learn a java programming language is by practicing Simple Java Program Examples as it includes basic to advanced levels of concepts. pow is the power means (s1,2) represents square of s1.‘ s2‘ represents length of the unequal sides of an isosceles triangle.(third side/base of isosceles triangle).‘ s1‘ represents length of the equal sides of an isosceles triangle.(first and second side).Program to Find Area of Isosceles Triangleīefore jumping into the program directly, let’s first see how we calculate area of Isosceles triangle.įormula for Altitude of Isosceles Triangle: (sqrt(pow(s1, 2) – (pow(s2, 2) / 4)))įormula for Area of Isosceles Triangle: (1 * s2 * h) / 2

In this article we will discuss about how to find area of Isosceles triangle. Keeps you in the practice for when you start writing bigger programs that require more detail.Area of a triangle java: In the previous article we have discussed Java Program to Find Volume and Surface Area of Cube Even if the method is blatantly obvious about its function, you should still include a docstring. Docstrings: I'm a stickler for docstrings.Returning the expression that is evaluated saves time, and looks cleaner. Return Expressions: It's better to return expressions than to just else: return False.sorted(sides): was a typo, so I removed the. Return len(set()) = isosceles(a, b, c):Īfter a very quick pass, here's what I have for you: Return is_triangle(a, b, c) and func(a, b, c) You could define a decorator that makes sure the input is a triangle: from functools import wraps Note that all functions need to use is_triangle. Return is_triangle(a, b, c) and len(set()) = 3 Return is_triangle(a, b, c) and len(set()) <= 2 Instead of manually checking all combinations of sides for equality, just use set to get rid of multiples: def isosceles(a, b, c): Return is_triangle(a, b, c) and a = b = c Try to put multiple checks in one line to return right away (but don't push it if it gets too complicated). Your other functions can also be shortened a bit.

The only thing you need to change in your calling code is to call this with is_triangle(*sides), i.e. This uses the fact that after the sorted, a is always the smallest side, as mentioned in the comments. The sides of a triangle are customarily called a, b, c. Instead, just explicitly take three arguments. This opens you up to obscure bugs, such as these ones, which are not covered in your tests: > is_triangle() I find it therefore weird to take a single sides argument, which could be of any size. Self.assertIs(isosceles(), True)ĭef test_equilateral_triangles_are_also_isosceles(self):Ĭlass TestScaleneTriangle(unittest.TestCase):Ī triangle has, by definition, three sides.

The sides of a triangle come in a list e.g. I've come up with a working solution, but I feel this could be greatly improved and/or simplified.
I've been fiddling around with some easy code challenges and there's one about determining if a triangle is equilateral, isosceles, or scalene.
