how to get points to expand a triangle
Posted on 2014-11-18
Dear Experts
I expect there is a straight forward formula for this, but I cannot find it.
In my VB6 app, I have defined a right triangle and the coordinates of the vortices are known.
The right angle of this triangle is in the lower left of the triangle.
I need to get the area of an expanded version of this triangle - expanded equally on all sides by 60 points (pixels in my app).
I have the area formula working well. Where I need help is how to find the points of the expanded triangle.
I can alter the x,y of the right angel easily enough; but am lacking the formula of how to find the y (for height) and x (for base). High School math is failing me,
Thanks
