In this challenge we will create a library of functions to apply the different formulas based on the geometry of triangles.
For each function, you will need to design the algorithm using either Pseudo-code or a flowchart, implement the function using the Python trinket provided below and use another algorithm to test your function.
Write a function called getPerimeter() that takes three parameters/arguments a, b, c (the length of each side of a triangle).
Your function should calculate and return the perimeter of this triangle.
Write an algorithm to test your function.
Your algorithm should:
- Ask the user to enter the length of the 3 sides of a triangle,
- Use the getPerimeter() function to retrieve the perimeter of the triangle,
- Display the perimeter of the triangle
Write a function called getArea() that takes two parameters/arguments corresponding to the length of the base and of the height of a triangle.
Your function should calculate and return the area of this triangle.
Write an algorithm to test your function.
Your algorithm should:
- Ask the user to enter the length of the base and height of a triangle,
- Use the getArea() function to retrieve the area of the triangle,
- Display the area of the triangle
Write a function called getAngle() that takes two parameters/arguments called angle1 and angle2 (the value of two angles in degrees)
Your function should calculate and return the value of the third angle: (180 – angle1 – angle2)
Write an algorithm to test your function.
Your algorithm should:
- Ask the user to enter the value of two angles in degrees,
- Use the getAngle() function to retrieve the value of the third angle,
- Display this value on screen.
Write a function called isEquilateral() that takes three parameters a, b, c (the length of each side of a triangle).
Your function should workout if the triangle is equilateral (if all sides have the same length) and return a Boolean value (True or False) based on its finding.
Write an algorithm to test your function.
Your algorithm should:
- Ask the user to enter the length of the 3 sides of a triangle,
- Use the isEquilateral() function to find out if the triangle is an equilateral triangle,
- Display a relevant message to the end user.
Write a function called isIsoscles() that takes three parameters a, b, c (the length of each side of a triangle).
Your function should workout if the triangle is an isosceles triangle (if any two sides have the same length) and return a Boolean value (True or False) based on its finding.
Write an algorithm to test your function.
Your algorithm should:
- Ask the user to enter the length of the 3 sides of a triangle,
- Use the isIsoscles() function to find out if the triangle is an isosceles triangle,
- Display a relevant message to the end user.
Write a function called getHypotenuse() that takes two parameters/arguments called a and b (the length of two sides of a right-angled triangle).
Your function should calculate and return the length of the third side (the hypotenuse) of the triangle knowing that:
Write an algorithm to test your function. Your algorithm should:
- Ask the user to enter the length of the 2 sides of a right-angled triangle,
- Use the getyHypotenuse() function to retrieve the value of the hypotenuse of the right–angled triangle,
- Display the value of the Hypotenuse.
Write a function called isRightAngledTriangle(), that takes three parameters a, b and c and works out if the triangle is a right-angled triangle or not. Your function should return a Boolean value (True or False) based on its finding.
Write an algorithm to test your function. Your algorithm should:
- Ask the user to enter the length of the 3 sides of a triangle,
- Use the isRightAngledTriangle() function to find out if the triangle is a right-angled trinagle,
- Display a relevant message to the end-user.
Write a function called getTriangleArea() that takes three parameters/arguments a, b, c (the length of each side of a triangle).
Your function will apply Heron’s formula to calculate and return the area of the triangle.
Write an algorithm to test your function.
Your algorithm should:
- Ask the user to enter the length of the 3 sides of a triangle,
- Use the getTriangleArea() function to retrieve the area of the triangle,
- Display the area of the triangle
