Question

Your math professor asked you to determine whether triangles are equilateral, isosceles, or scalene triangles. You need to write a MATLAB program that accepts the side lengths for sides A, B, and C of a triangle and compares the side lengths in order to determine if the triangle is equilateral, isosceles, or scalene. Each triangle will only be classified as a single type based on the definitions below:

1. An equilateral triangle is a triangle in which all three sides are equal

2. An isosceles triangle is a triangle that has two sides of equal length.

3. A scalene triangle is a triangle that has three unequal sides

For example, if a triangle has three sides of equal length, the code will only classify that triangle as equilateral, rather than both equilateral and isosceles.

1) Write a MATLAB script file that:

a. Takes numeric input from a user of the side lengths for sides A, B, and C of a triangle, where each side length is in centimeters. You may assume the user will enter valid values for the side lengths.

b. Uses a conditional structure to compare the lengths of the triangles, and output whether it is an equilateral, isosceles or scalene triangle.

Answer 1

a=input('Enter A:')
b=input('Enter B:')
c=input('Enter C:')
if(a==b && b==c)
   disp('Equilateral triangle')
elseif((a==b) || (b==c) || (a==c))
   disp('Isosceles triangle')
else
   disp('Scalene triangle')
end
