Right angled triangle

I may be missing something obvious (pop-up menu?), but I can only create isosceles triangles, and would like to make right-angled ones. If someone could give me a hint, I would be grateful.

Thanks

Well - I´d go: pick pencil tool set one initial point - hold shift key down while introducing the next 2 points - by this Intaglio maintains rectangular lines - to close the triangle hold alt-key down and click first point - or hit enter and click “Closed” at the stroke tab.

Cheers

Maybe you should have said that Intaglio maintains 45º diagonal
lines. ;-))

One can also use the straight line tool

Not sure how your advice help with right-angled triangles. :wink:

Thanks: that helps. Is there a way to apply an interior color: the Fill command doesn’t seem to do it

No? Hit the color square at “fill” palette (is “white” by default) go to the color wheel (or whatever you prefer to choose from) and pick a new/other one.

The same distances from a point, 45 southwest and 45 southeast,
that’s a right isosceles triangle in standard Euclid position. :-))

Seems I´m lost in translation - but I thought the thread starter didn´t want a isosceles triangle but a rectangular one and there shouldn´t be any 45° angle except for the “set square®”. No?

No: The sum of the angles in a triangle is 180º. We allocate 90º for
the angle that the OP wanted to be a right angle which leaves 90º for
the other two angles which, since the OP wanted the triangle to be
isosceles, must be both equal to 45º.

I think that the difficulty is that we do not look at our triangle in
the same position.

I look at the vertex with the 90º angle as being at the TOP. Then, on
the one hand, I go SW from the top and on the other hand, back again
from the top, I now go SE. The basis of the triangle is thus West-
East at the BOTTOM.

                 TOP
                 /    
 SW       /             SE
      /                 
         o–––––––---o
                 basis

The top angle is 45º SW + 45º SE = 90º

I am going to try to attach a pdf.

Well - I´m a qualified designer and know my maths - but where did he say he wants a isosceles triangle?

  1. Draw a rectangle (R key)
  2. Switch to the Point Selection tool (X key)
  3. Select one point
  4. Press Delete or Backspace. The rectangle becomes a right-angled triangle.

I had assumed that “ones” referred to “isosceles triangles”. My mistake.

Fantastic! That’s the sneaky sort of thinking I was hoping for.

Many thanks
