How to make a constant length segment?

HarishTella
Is there a simple way to:

get point A to move only on the Y axis
get point B to move only on the X axis
and keep the segment A to B a constant length.



I feel like I'm missing something really obvious.

Thanks.

Hello,

You will have to imagine a construction doing exactly that.
You can then  save the result in a macro construction

By the way you may also want to use the magnet tool to get horizontal or
vertical lines/segments.

I will start the construction from point A and a circle of center A and
a fixed radius.
I am curious if then the result could be recorded in a macro-construction.

Ah, never mind! I did the construction then recorded the whole in a
figure packaged with a macro-construction. It is in attachment.

When open, you will get the figure with the expected effect, plus a
macro construction: the macro construction expected as unique argument
the length of the segment AB, then it compute the whole triangle with
two side constrained in x-axis and y axis. So it works nicely.

Ah, I see. Forgot about using a circle. 

Thanks.

In paper configuration you will use a compass, with interactive geometry
software you use circle when you need a fixed length.
