Constructor & Destructor Documentation

Triangle::Triangle	(	int	b,
		int	h,
		int	x,
		int	y
	)

Overloaded constructor that takes in a base, a height and an (x,y) coordinate.

Parameters:

	b	The base of the triangle (must be greater than 0)
	h	The height of the triangle (must be greater than 0)
	x	The X coordinate of the triangle's center point in 2D space
	y	The Y coordinate of the triangle's center point in 2D space

Triangle::Triangle	(	int	b,
		int	h,
		Point	c
	)

Overloaded constructor that takes in a base, a height, and a center Point.

Parameters:

	b	The base of the triangle (must be greater than 0)

Member Function Documentation

double Triangle::getArea

(

)

const [virtual]

Virtual function overridden from Shape. Returns the area of the triangle as (1/2)*base*height.

Precondition:

The base and height must be set to valid numbers.

Postcondition:

Does not change the object

Returns:

The area of the circle as a floating point number.

Implements Shape.

string Triangle::getType

(

)

const [virtual]

Virtual function overridden from Shape. Returns a string indicating what type of shape this object is.

Precondition:

None

Postcondition:

Does not change the object

Returns:

The string "Triangle"

Implements Shape.
