I want to divide a rounded triangle into 2 equal halves vertically and then fill 2 different colors in the two halves. I want to make the shape shown below in the image. Anyone please help me out with this using illustrator.

I want to make this shape


Use a guide to mark the center line, then use a rectangle to draw over one side, select all and use Pathfinder > divide tool. Then un-group, delete extra part of rectangle, and you should have two equal parts of the triangle you can color.

Ok here is how to make the triangle and then split it.
Again start with some guides.
then draw the basic shape without any round corners.
then get your selection tool.
hold down ctrl, and click on the circles on the corners you want to round.
you will have to play with the radius you give each corner to fit your shape
then refer to the above instructions on how to split the triangle in half

  • Thanks for the answer. But I want the exact shape that I have shared in the question. Please refer that and help me with it. – Anubhav Sarangi Jan 10 '18 at 16:54
  • This method will work no matter what shape triangle you draw. If you are unable to draw the rounded triangle in question that is completely different situation, and not a part of your question. – John Burgess Jan 10 '18 at 16:55
  • I tried doing it but the above method works with normal shapes(without rounded corners) but with rounded shapes when I divide it using pathfinder tool there are no rounded corners in the shape i.e. it is restored to normal shape (without rounded corners). – Anubhav Sarangi Jan 10 '18 at 17:04

    I actually never use the Scissors tool, ever - I find it too imprecise. I'd draw a line down the middle and then align the two objects.. then Pathfinder Divide. You don't need a rectangle... a single path works great for Divide. – Scott Jan 10 '18 at 17:38

    @AnubhavSarangi did you watch my animation?? It clearly works fine. I created the entire shape and split it without any issues whatsoever. Where in my animation did I use the Rounded Corner effect??? You sure seem to be asking a lot of others without any sense of gratitude or effort on your own. This site is not a "tutorial on demand" site. – Scott Jan 11 '18 at 5:11

Just another video of how I'd handle it from scratch....

Not necessarily better or worse than the other methods. Same general principle. However starting with a rounded rectangle offers the top curves easily. Then it's just a matter of creating the center point and curve. And with a single path you can align to the center and use Pathfinder > Divide easily.

Of course, if you have VectorScribe from AstuteGraphics installed, it's dead simple to get the shape from a standard triangle using the Dynamic Corners options. And I would use far more tool shortcuts than the video shows. I had to remember where tools are in a couple places because I'm more accustomed to their shortcuts.


An easy solution would be to use the scissors tool (C).

Pick the two points you want to split then click once on each with the tool. Now you have 2 equal halves. Select each in turn and join the open ends using Ctrl+J and color each half as desired.

Once done you can select both and group them using Ctrl+G

Here's how to do it on a shape like the one you want.

    @AnubhavSarangi The method applies to any shape. – Ovaryraptor Jan 10 '18 at 17:12
  • Thanks for the solution. Please help me with drawing the shape with rounded corners. The clip shown above shows how to divide and color it with 2 different colors but doesn't show how to draw the shape. – Anubhav Sarangi Jan 11 '18 at 4:04
