Triangulum and Triangulum Australe
The Right Triangle & Southern Triangle
Coincidentally there are two constellations dedicated to the triangle. Sorry no circles, hexagons, rectangles, trapezoids or any other type of shapes need apply. A rhombus almost made in, but the astronomers couldn't dig the funky four corners, so it was given a pink slip.
So why are triangles so important to astronomers? Because they are a fundamental shape that allows scientists to calculate distances with shadows and starlight. Basically all other shapes can be broken down into triangles, which lead to the "Advanced Study of the Triangles" aka Trigonometry. Long story short, the careful study of triangles allowed mankind to sail around the world.
The Northern Triangle has its stars in the general shape of Right Triangle. But it simply goes by the name Triangulum the Triangle. Triangulum Australe the Southern Triangle is in the general shape of an Equilateral Triangle.
The flag Triangulum the Triangle is composed of the colours yellow and orange. Since the Triangle does not completely dominate a band it has two central overlapping stripes. Triangle is best viewed during the month of November. Although it is considered the 'northern' triangle since in the Northern Skies, Triangle is a part of the Southern Galactic Cluster. Consequently the Astrological icons are green.
Our solar system is a wacky planet like Uranus. Our system's planets orbit the Milky Way Black hole at an extreme angle 'out of tilt' with direction of the Milky Way Galaxy.
