Maybe it is Curvilinear rectangle
If a triangle is obtuse, the orthocenter of the triangle actually lies outside of the triangle. If the triangle is acute, the orthocenter of the triangle lies on the inside of the triangle
A triangle can be constructed into any of the given formats.
If a triangle has a right angle, it is a right triangle.
An obtuse angled triangle.
It has three sides.
Curvilinear seems to fit the description of a cone
Oh honey, that's not a triangle, that's a whole other shape called a "curvilinear triangle." It's like a regular triangle, but with a sassy curve thrown in there for some flair. So, technically speaking, it's not a triangle at all, but nice try though!
A car turning on a curved is known as curvilinear motion.
A curvilinear pattern is a curvilinear shape ( a shape made completely of curved lines. no straight lines/edges) repeated across a plane.
How about a smile? (Doesn't curvilinear mean rounded?)
A Curvilinear cost is a cost that changes with volume(activity) but not at a constant rate.
The many turns in what was normally a road with mostly straight lines gave rise to the engineer's description of the road as curvilinear . The arc in the building was curvilinear .
the wrought ironwork formed into curvilinear, whiplash lines
A random walk is opposite in all senses. A straight line is only a curvilinear path with all the "higher order" terms set to zero.
Translation, rotation and curvilinear motion
