PROBLEM DESIGNING TRIANGLE

[Anonymous]

HI.. having some challages creating an equal line triangle..  Been though many videos but can't seam to get it ..  thanks 🙂

1. Draw a line.
2. Draw lines at the end points of the first line.
3. Dimension the angle between the first line and each of the end point lines to equal 60 degrees.

Like @etfrench but I've dimensioned / constrained the sides. A faster, but less intuitive way is to use  the "Circumscribed Polygon" function. I've shown both ways in this little screencast.

Great I will try that. Thanks for the support 😄

there's always the polygon sketch tool also.

draw a line, dimension it the length you want the sides to be.

draw two more lines, one attached to each end of the first, and the ends of those connected.

then dimension them using d1 as the dimension (that ties the length of those to the length of the first line)

now if you change the first line length, the others always update.

you can also just draw three lines in a general triangle shape, then dimension one, then the other two to d1.

im uploading a screencast now. takes longer to type this than do it;

@laughingcreek.  ... Like I've mentioned in post number 3 😉

I don't see you mention that method at all. The 3rd way you mention involves using the angle.
You never mentioned using one dimension, then referencing it, so the triangle always stays equal.
But there's lots of ways, sorry you felt the way i showed was duplication of your way. ;-]

@dieselguy65: I agree that my comment was foolish and I'm an idiot. But my comment was for @laughingcreek. I did mentioned angle in my post because the first solution was based on angles, but my post was based on dimensions + constrains in the first part of the cast and the polygon tool as a 2nd solution in the last part. You did a 3rd way by using only dimension. No need to pull you into the discussion.

But in the end I apologize for my bad style and my bad mood.

It's all good here. The more ways e show to do it, the easier it may be
on beginners. One way may just turn on a light bulb for them so to speak.
But, as has been said before, there's a free guys posting questions here
that are so basic, if they just done a few tutorials they would already be
way ahead.
Each way posted has benefits, even the inscribed polygon works, just not
as intuitive as was pointed out. But in some instances it makes sense.

You need to go back to high school geometry, if you draw two circles with equal radius. 1 radius a part, the centers of the circles and the point where they meet form an equilateral triangle.

the easy way to do that is to draw a line equal to the length of the side then draw a circle at each end with the radius equal to the length of the line.  then draw in your other two lines.

thats maybe the easy way on paper.

compared to the other methods posted here, thats alot more steps
