I know, shitpost and all, but this is possible in non-Euclidean geometry
A triangle with 90° angles, yes.
But not a four sided TRIANGLE. That itself is a contradiction.
One of the angles is 180 though so imagine what the two sides joined there would look like. After all this isn’t to scale.
You can’t make a 3 sided object with 4 sides. It’s no longer a triangle and is a square. It’s the definitions themselves. Non-euclidian geometry would allow the angles to equal more than 180°, but not to “add a side”.
“Not to scale”
. .
Incase that is still a mystery to you, that means that the drawing is visually inconsistent with the finished part. That 180 degree ‘corner’ is effectively a straight line, if drawn to scale.
Mathematicians dont want to to know this one strange trick, hide a secret corner of 180 degrees in any triangle to instantly make it a quadrilateral, without even changing the shape!!
Stop revealing my topology secrets!
I am ungovernable
Sum of interior angles of a triangle should be 180° so this is not a triangle. It is a square or maybe 2 triangles
The 180° angle is just a (really weird) way of representing a long, straight, line. The rest of the angles add up to 180°.
