How to create a triangle in Visual Studio?

Question

I want to create a triangle with Windows Form in Visual Studio (c# code). In Form1 I have 3 textboxes that the user enters the lengths of the sides of the triangle and 1 "Enter" button. When the button is pressed, Form2 is opened and a triangle is drawn when the mouse is clicked. Can somebody help me?

If you want to draw shapes and figures, you can try the Leadtools annotations SDK (https://www.leadtools.com/sdk/annotation). I've used them before and they have a lot of options for customizing how they are rendered and behave. It supports WinForms, but also JavaScript like on their live demo (https://demo.leadtools.com/JavaScript/Annotations/) Here's a tutorial they have for WinForms: https://www.leadtools.com/help/sdk/v21/tutorials/dotnet-winforms-draw-and-edit-annotations-on-images.html
