It is the shape formed by three non-collinear points on the surface of a sphere which are joined together by straight lines in which two of the sides are of the same length.
An example might be a triangle from the earth's North pole to two points on the same latitude - specially the equator.
On the surface of a sphere, find any three points which are not on a great circle. The shape formed by joining the three pairs of points using arcs of great circles is a spherical triangle. The triangle is isosceles if two of the arcs are of the same length [and the third is not].
A great circle, in this context, is a circle on the surface of the earth and whose centre is at the centre of the earth.

Isosceles spherical triangle?
Yes, they do exist.
What triangle has one right angle and can be an isosceles?
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
What is a triangle with sides 11cm 15cm 11cm?
Isosceles
Does an isosceles triangle have a 90 degree angle?
An isosceles triangle can have a 90 degree angle, but doesn't necessarily. Similarly, a right triangle can be an isosceles triangle, but isn't necessarily.
How many pairs of perpendicular lines does an isosceles triangle have?
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
Isosceles spherical triangle?
Yes, they do exist.
Triangle with two 60 degree angles?
equilateral triangle (and so, if it is in Euclidean (plane) space, it has 3 angles all of which are 60°) otherwise (in Hyperbolic or Spherical space) it is an isosceles triangle.
How do you find the altitude of a right triangle of an isosceles triangle with370.5 equal sides and a 57 degree 24 sec angle?
A right triangle that is also isosceles cannot have an angle of 57 deg 24 sec unless it is in spherical - as opposed to plane, or flat - space.
Is an acute triangle sometimes an isosceles?
An acute triangle can be an isosceles triangle, but it doesn't have to be. An isosceles triangle can be an acute triangle, but it doesn't have to be.
What is an example of an isosceles triangle?
isosceles triangle
What does a right triangle and an isosceles triangle have in common?
A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
Ans isosceles triangle is a triangle that has?
An isosceles triangle is a triangle that has two equal sides.
Are isosceles triangle sometimes an equilateral triangle?
Are isosceles triangle sometimes an equilateral triangle
How do you draw an isosceles scalene triangle?
You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.
How is an isosceles triangle related to an isosceles trapezoid?
how is an isoscelels trapezoid related to a isosceles triangle
What is the same about an isosceles triangle and an isosceles trapezoid?
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
If a triangle is obtuse then is it isosceles?
An obtuse triangle is not necessarily isosceles, but it can be.
