## How to draw a triangle within a polygon

Hi

I'm trying to draw a triangle within a 6 sided polygon, and then within the triangle, another series of three small triangles meet at the centre (and are equal). You can see my hatchet attempt below. I am coming into problems at a number of stages, and I don't know if what I am doing is the best approach - this is not how I would draw this on paper!

I used the triange tool to create the first inner triangle. But then I had trouble lining up the corners. And when I used the path menu to divide the polygon below, I discovered I had overextended my corners. I was expecting to have to use the scissor tool to cut the joined corners of the smaller triangles, so I could reflect them to create the inner three trianges - which are meant to be all joined together neatly, no spaces, and perfectly aligned. Instead, because of the overshoot I had my distinct triangles, but when I reflected them, they were all out of whack. I tried to fix them by aligning the corners vertically and horizontally, but now I have spaces. I'm trying to fit these all neatly and perfectly within the shapes.

I then tried to replicate how I might draw a triangle on paper, by drawing a line from the midpoint of one side of a polygon to a vertice, but all I ended up doing was deleting an anchor point on my polygon. I couldn't find any info online on this!

Any hlp would be appreciated.

thank you

Rebecca

Actually, something more like the way you would do it on paper might be easier. Here's a possible way, using Smart Guides to help you: 1) After drawing the hexagon with the Polygon Tool, select the Line segment Tool and And draw between alternate corners to make the equilateral triangle shape. Smart Guides will show you when you're exactly on each corner.   2) Still with the Line Segment Tool, draw a line from each vertex of the triangle to the opposite corner of the hexagon.   3) Select one of ...

I would suggest the next way: 1. Draw a hexagone and rotate it to set sides vertical. 2. Duplicate it (Ctrl+C > Ctrl+F) and delete the needless points using Pen tool (Pen-). 3. Select all and click Divdie button in Pathfinder panel. Ungroup. Now you can delete the main triangle if you don't need it anymore. 4. Duplicate the external triangles (Ctrl+C > Ctrl+F) and reflec them using Reflect tool. Set the axis for each reflection as the respective main triangle side.   For the best appearance s...

You're welcome, Rebecca.   I keep finding new ways to do this:   1) Using the Line Segment Tool or the Pen Tool, connect two points skipping one between, and the same first point to the center point.   2) With both line segments from step 1 selected, click the center point with the Rotate Tool.   3) Click and hold on one of the endpoints of the longer selected line, hold down the opt/alt key, and drag in either direction around the hexagon, bypassing the first vertex and connecting to the second...

3) Select one of the paths from step 2, then choose the Scissors Tool, and when Smart Guides shows that the tool is over the intersection of the three lines, click to cut, select the portion of the line that you don't want, and delete it. Repeat with the other two paths.

4) You should be left with the design you want.

For the best appearance set rounded corners in Stroke panel.

I added here some coloring to show the result better.

Thank you Anna and Peter. I ended up using Anna's solution, but both were very helpful, and much easier!

thanks again

b) ClickDrag with the Line Segment Tool from the centre to each corner.

You're welcome, Rebecca.

4) Press cmd/ctrl + D to repeat the rotation and duplication of the two lines.

Since you already have a usable answer, this is just for fun.

For my part you are welcome, Rebecca.

I meant it when I said at least three.

You can also, just based on the original set of hexagon and triangle (with Round Corners, of course):

1) Create the hexagon and rotate it by 30 degrees,

2) Create a triangle with the same Radius and snap its top Anchor Point to the top Anchor Point of the hexagon,

3) Copy the triangle from 2) and lock either, then (with the other one selected) Object>Path>Add Anchor Points, then deselect and DirectSelect the new middle Anchor Points (avoiding the hexagon centre if it is set to show, you can Click or Click Drag over each; if it is hidden you can just ClickDrag over all three middle Anchor Points), then Object>Path>Average (with Both ticked), then unlock the other triangle.
