Hi,

I need to create a triangle based on a height value given by the user.

The base of the triangle is calculated with:

and the method I am trying to use the make the triangle is:private int getTriangleWidth( int triangleHeight ) { return 2 * triangleHeight - 1; }

If the user inputs 5, this results with a triangle that looks like this (I haven't included my driver method that actually tests the output):private void printTriangle( int height, int margin, boolean pointUp ) { int base = this.getTriangleWidth( height ); int m; int n; int o; if( pointUp ) { for( n = 0; n < height; n++ ) { for( o = -1; o < n; o++ ) { System.out.print( "*" ); } System.out.println( " " ); } } }

*

but I need an equilateral triangle: if the user inputs 5, it should have a base of 9 and a height of 5.

I understand that in my code above I don't have it depending on the base value at all but I'm not sure how to include it in or how to get the whitespace to come before the * in an even way so that I get my desired result.

Any hints would be wonderful
