Its imposible in Euclidean Geometry, but it can be found in spherical geometry, such as the Earth. If two people a certain distance away from each other are standing on the equator, if they both walk north (perpendicular to the equator ) at the same time, they would meet at the North Pole at a right angle to each other.

A triangle cannot contain 3 right angles because, by definition, the total of the 3 angles that make up a triangle equals 180 degrees. Three right angles, 90 degrees each, would equal 270 degrees, which does not define a triangle.
If you mean 3 angles that are the same that make up a triangle, then you are talking about three 60 degree angles(3 x 60 =180) and that is called an equilateral triangle.

The only triangle with 3 right angles is the triangle that is one side of a pyramid.
The pyramid is made up of 4 triangles (plus a square base) and the angle at the apex is 90 degrees.
In this situation, each of the triangles could be said to have 3 right angles.
Thank you

This is impossible for a real triangle on a plane, since, as you
probably know, the sum of angles must be 180 degrees. But it is
possible in spherical geometry, where we use the word "line" to mean a
great circle (a circle around the sphere whose plane goes through the
center of the earth).
Imagine starting, say, at the North Pole, walking some distance in a
"straight line," turning left 90 degrees, walking some distance, then
turning left 90 degrees again, and getting back where you started. Can
you find a way to do this, and end up 90 degrees from your original
direction?

In plane geometry, a triangle has a total of 180 degrees with all 3 angles. A right angle has 90. Three times 90 = 270.
I wonder if in spherical trig, that might be possible, but I don't think it's any different.

Three sides of a square.
Three right angles = 270 degrees. A triangle is only 180 degrees. At most it can only have one right angle, and it is called a right angled triangle.
However, you can have a triangle where all three angles are the same. That is an equilateral triangle.

A Triangle can have a maximum total of all angles of 180 degrees.
There is no such thing as a 270 degree triangle.
The only triangle with 3 right angles is an illusion.

Some of the three angles of a triangle is always 180 degree, so a triangle whose sum is 270 is not possible.

I don't know what the name of it is but if the triangle is built on a sphere, it could have three right angles. (looking) It's a spherical triangle.
