It does not mean anything in particular.
i dont know but i have a 3 dotted birthmark in the shape of a triangle. i wish i knew what it meant. I myself would also like to know what this means, I was also born with a triangle birthmark on the back of my head. i also have one on my right breast lol i was wondering what it meant cuz its a strange birthmark to have : an equal angular upside down triangle formed from three dots
I read it means you have Sirian blood line. Your a
birthmark on right foot is it good or bad
Number 7 birthmark
A triangle with a 90 degree angle.
It means that it is a right angle triangle
If you mean angles then it is a right angle triangle or an isosceles right angle triangle
Birthmarks have been studied and interpreted for centuries. A heart shaped birthmark tends to mean you will be lucky at love. how the shape is situated (upside down, right-side up, tilted, on its side) is less important than where the mark is.
I am guessing you mean a right angled triangle. The hypotenuse is the longest side on a right angled triangle. So it is the side facing / parallel to the right angle.
If you mean can a triangle have 3 equal sides and the answer is yes it can and it is called an equilateral triangle.
the longest side of a right triangle
If you mean what type of triangle has perpendicular lines then it is right angle triangle.
