tick marks for sides of triangles?

Brian Fulton shared this question 9 months ago

I'm wanting to show that 2 triangles are congruent and use the standard tick marks on the sides of the triangles. 1 tick, 2 ticks, and then 3 ticks. Is there an easy way to do this? I found how to get the angle arcs (1, 2 and 3), but I haven't found a quick way for the sides.


Thanks,

Right click on one side of the triangle. A context menu opens:

-Select Object properties.... (v.5) or Settings (v.6 / apps)

- Select the Style tab of the appearing panel

- Select one of the available Decorations

Thanks. Is there any way to make these tick marks larger besides changing the line thickness?

show attachment for more dynamic by the ticks/Decorations

Note: I'm not sure the command AreCongruent() works always correct

(for example equilateral and isosceles triangles AreCongruent() seams to have a bug)
