Write A Program To Print Area Of Triangle In C
C Program to Find Area of Any Triangle using Heron's Formula. C Program to Calculate Area of Any Triangle using Heron's Formula Write a C program to find the area. C Program for Beginners: Area of Right Angled Triangle Right angle Triangle Definition: Triangle having one angle of measure 90 degree is called Right angle Triangle. Set the user’s input to the variable you created representing the first side of the triangle. Repeat the last 2 steps twice more, once for each of the remaining 2 sides of the triangle. Use a series of nested if / else statements to determine if the triangle having side-lengths as set by the user is an EQUILATERAL, ISOSCELES, or SCALENE triangle.
As your professor suggested, you should look at: You should also look at: Algorithm: Solve for all angles, a1, a2, a3 (see the article above) If you can't find a solution: Output 'Error: Not a valid triangle' Else: If (a1 == a2) && (a2 == a3): Output 'EQUILATERAL' and stop If (a1 == a2) (a2 == a3) (a1 == a3): Output 'ISOSCELES' and stop Output 'SCALENE' and stop Also note: Be careful about 'equality' with floating point ( float/ double) values (such as angles). If you are doing such a comparison, you should usually use this instead: abs(x - y). The logic falls out neatly from the definition of these different types of triangles, which as the professor notes, is information readily obtained from Wikipedia.
It just involves a simple comparison of side lengths; you don't have to go as far as angles. But I'll give you some help with the 'not a triangle' condition. Patch Solidworks 2006 on this page. Don't be afraid to put on your math hat here and go wandering in, a little logic isn't a bad thing for a poli sci student to endure every now and then.:-) For the sides to make a proper triangle, for each pair of sides (I'll call them f and g), they must add up to greater than the third side's length (I'll call it h). If you're dealing with equilateral triangles, you automatically know this condition is met (why?). If you're dealing with isosceles or scalene triangles, you technically only need to check the smaller two sides against the largest side, and if it's true for them, it's true for the other two cases as well (why?).
