It's an equilateral triangle whose legs are all 90-degree arcs.
Here's a quadrantal triangle on the earth:
-- Start at the north Pole.
-- Draw the first side, down along the north 1/2 of the Prime Meridian to the equator.
-- Draw the second side westward along the equator, to 90 degrees west longitude.
-- Draw the third side straight north, back up to the north Pole.
Each side of the triangle is 90 degrees, each interior angle is also 90 degrees,
and the sum of its interior angles is 270 degrees.
Pretty weird.

What is formula of quadrantal spherical triangle?
There is no single formula: there are several, depending on what information you have and what you wish to know.
What is the contribution of menelaus to trigonometry?
He defined the spherical triangle
What is a polar triangle in spherical trigonometry?
for any spherical triangle on any sphere there associated another triangle called the polar triangle associated with this spherical triangle with the property that the sum of any angle (or side) of one of these two triangles and the length of the side (and the angle)of the other triangle is alway equil to 180 degrees
What are the 2 branches of trigonometry?

What is the difference between plane trigonometry and spherical trigonometry?
Trigonometry is the study of plane and spherical triangles. Plane trigonometry deals with 2 Dimensional triangles like the ones you would draw on a piece of paper. But, spherical trigonometry deals with circles and 3 Dimensional triangles. Plane trigonometry uses different numbers and equations than spherical trigonometry. There's plane trigonometry, where you work with triangles on a flat surface, then there's spherical trigonometry, where you work with triangles on a sphere.

Is a triangle still a triangle if it has 2 obtuse angles?
In spherical trigonometry this is possible

Why does spherical trigonometry important?
The earth, which we live on, is approximately a sphere. It is important, therefore, to know spherical trigonometry.
What is the meaning of spherical triangle?
Spherical trigonometry is a branch of spherical geometry, which deals with polygons (especially triangles) on the sphere and the relationships between the sides and the angles. This is of great importance for calculations in astronomy and earth-surface and orbital and space navigation.
How many kinds of trigonometry are there in mathematics?
Two types of trigonometry are recognized: planar and spherical. Planar is 2-dimensional, while spherical is 3-dimensional. Though these are different fields, spherical trigonometry is really just an application of planar trigonometry in several planes.
What is the importance of spherical trigonometry in math?
Historically, it is because we live on a planet which is approximately spherical. 2-dimensional trigonometry was adequate for relatively small shapes where the curvature of the earth had negligible effect. For larger shapes the spherical nature of the earth was important and therefore, so was spherical trigonometry.
What is the importance of spherical trigonometry?
For navigational purposes
