Sat, 08 Dec 2018 14:03:01 GMTThe Challenge is to divide a square into 4 equal parts with three cuts.
All you need do is present you final image (JPG, PNG, WEB, XAR).

Here you are for 2 and 4 cuts:

Note: in Xara you don't need to use any cuts whatsoever.
Can you describe how?

Now the Challenge is to final the second triangle with the same values, as shown:

The usual rules apply, Xara functions, simplest you can make and with no calculations.

He was shown a fence of length 400 PackOx (px) and given a single stake, which would define the top corner of his land.
He was to place it on the far bank of the canal and the boundary triangle would then define his land for tillage and the length of bank on the nearside, from where he could fish.

His Challenge was to work out where to place his single stake.
Where did he choose and more importantly why?

Mon, 03 Dec 2018 16:57:56 GMTUsing the Xara ellipse too, create a Red ellipse of width (major axis) 400px and height (minor axis) 200px.

The Challenge is to find the focal points F1 & F2 without any calculation.

Your "proof" will be any triangle with a base of F1F2 (346.4px) and apex on the rim of the ellipse will have a Perimeter of 746.4px.

P(F1AF2) = P(F1BF2) = P(F1CF2).

Knowing the length between the focal points and with a rope or twine the length of the perimeter and tied into a single loop, it would be possible to inscribe the ellipse to be the basis of an elliptical pond or garden feature.

The path from one focus to the rim to the other focus is always goings to be 400px.
This is the reason whispering galleries work; any sound made at either focus is concentrated at the other one.

Sun, 02 Dec 2018 16:46:56 GMTFollowing Marco's great answer for the given sides of a triangle, https://www.talkgraphics.com/showthr...lk-in-the-Park, this Challenge is extended so all three sides are different lengths.

I don't care what the dimensions are, I want a Xara solution that is repeatable and simple and does not require calculation or approximation.

Go wild!

Fri, 30 Nov 2018 16:49:21 GMTThis Challenge should be very easy for those who have been following the Triangle Challenges.

Using Xara, construct a triangle of sides 200px, 400px and 400px, in the simplest way possible without calculation.

In your answer, advise the perimeter of your triangle, using Xara's P reading.

Take the same Triangle (B318px/H412px) [S90S].

Now instead of the two lengths being at an angle of 90°, I want the simplest means to change this interior angle to one of 142° [S142S]
If you are keen, produce a second triangle with an interior angle of 17° as well. [S17S]
