What is quadrantal triangle in spherical trigonometry?
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.
Which set of points does not determine a spherical triangle?
Three non-collinear points do not determine a unique spherical triangle.
Difference of plane and spherical triangles?
A plane triangle looks like a common triangle. A plane triangle is solved with linear units. A spherical triangle is found inside of a sphere. This type of triangle is solved with angular units.
In spherical geometry which indicates the possible number of right angles a triangle may have?
All three interior angles of a spherical triangle may be right angles.
What is the contribution of menelaus to trigonometry?
He defined the spherical triangle

Isosceles spherical triangle?
Yes, they do exist.
Is a triangle still a triangle if it has 2 obtuse angles?
In spherical trigonometry this is possible

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 solutions to an oblique spherical triangle?
The solutions do depend on what the questions are!
How do you slove for a spherical triangle?
A spherical triangle is not a question or a puzzle that you can solve, or even slove! You need to specify what information you have and what you wish to solve for: angles, lengths of sides, perimeter, area and so on.
What is quadrantal?
a colorblind disease known by cb
What do you call a triangle with two obtuse sides?
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".
