Well, mathematically speaking the total degrees of a triangle adds up to 180o. So, you have used up your 180o ( right angle = 90o ) with two right angles and you have to account for another angle to have a triangle.
AnswerAll that in the above answer is correct: but it is for 'Plane' geometry, so-called because it is in a 2-dimensional plane.However, another type of geometry is 'Spherical' geometry, called because it is in 3-dimensions like a sphere. It is used for long-range navigation on the sphere of the earth, and also in space navigation. In spherical navigation there can be more than 90O in every corner.
Surveying is one common example of the use of Plane geometry, while Spherical geometry is used for Spherical navigation, also called celestial navigation.

Is it possible to draw a triangle with three right angles on a sphere?
It is impossible to have a triangle with 3 right angles. It is possible to draw a triangle with three right angles on the surface of a sphere: www.metacafe.com/watch/769025/270_degree_triangle_yes_3_right_angles
Is it possible to draw an equiangular right triangle?
No, it is impossible to draw an equiangular right triangle. An equiangular triangle has three 60o angles. A right triangle has one 90o angle, and two 45o angles.
Can you draw a triangle with 2 right angles?
Yes you can. The problem is on what surface you draw the triangle. On a plane this would be impossible, but if you do it on a spherical surface then you can even draw a triangle with 3 right angles.
Is it possible to draw one triangle with two right angles?
No it is not possible to draw 1 triangle with 2 right angles because the angles in a triangle should equal to 180 degrees
Which type of triangle is impossible to draw?
right obtuse triangle
How do you draw a triangle with 1 acute angle and 2 obtuse angles?
Impossible
Is it possible to draw a triangle with two right angles?
No
How can you draw a triangle with 2 right angles?
You can't.
Which of the following triangles are impossible to draw?
a right obtuse triangle, a scalene triangle, and a right equilateral triangle
What kind of triangle is impossibal to draw?
If the sum of all the angles(inside the triangle) is greater than 180 degrees then it's impossible to draw it.
How do i draw an obtuse right triangle?
There's no such thing as an obtuse right triangle ... that's why it's so hard to draw. -- the three inside angles of every triangle add up to 180 degrees; no more, no less -- a right triangle has a right angle in it ... that's 90 degrees -- an obtuse triangle has an obtuse angle in it ... that's more than 90 degrees -- if you had both of them in the same triangle, those two angles alone would add up to (90) plus (more than 90) = more than 180. -- That's impossible. So an obtuse right triangle is impossible.
What triangles is impossible to draw right obtuse triangle right scalene triangle acute isosceles triangles or a obtuse scalene triangle?
A triangle can only have 1 right angle or 1 obtuse angle in it because its 3 interior angles add up to 180 degrees
