Not in traditional, 2 dimensional, euclidean geometry, because a triangles angles always equal 180º .
However, there is a branch of Geometry that deals with a coordinate system on a sphere, instead of a plane, and in spherical geometry a triangle with three right angles is very much possible. Consider, for example, the triangle bounded by the Prime Meridian, 90o west longitude, and the equator.

Can a triangle have three right angles?
A triangle can never have three right angles
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
What type of triangle is angle abc obtuse acute or right?
If one of the angles is 90 degrees then it is right ange triangle If one of the angles is obtuse then it is an obtuse triangle If the three angles are 3 different acute then it is a scalene triangle If two of the angles are equal then it is an isosceles triangle If the three angles are equal then it is an equilateral triangle
What does a right triangle means?
Every triangle has three interior angles which total 180 degrees. A right triangle has one of the angles as 90 degrees.
How do you determine that the triangle is a right triangle through the 3 vertices?
If one of the three interior angles is 90 degrees then it is a right triangle.
Can a triangle have three right angles?
A triangle can never have three right angles
Does a right angled triangle is one angle always a right angle?
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
All angles are right angles or a triangle has four sides?
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
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
How many angles are in a right triangle?
Three.
Is an equilateral triangle all right angles?
No, an equilateral triangle as three 60 degree angles.
What type of triangle is angle abc obtuse acute or right?
If one of the angles is 90 degrees then it is right ange triangle If one of the angles is obtuse then it is an obtuse triangle If the three angles are 3 different acute then it is a scalene triangle If two of the angles are equal then it is an isosceles triangle If the three angles are equal then it is an equilateral triangle
What does a right triangle means?
Every triangle has three interior angles which total 180 degrees. A right triangle has one of the angles as 90 degrees.
How many right angles do a right triangle have?
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
How many right angles has a triangle?
As there are 180 degrees in every triangle, and you have to have three angles, you can only have one right angle.
Do rhombuses have right angles?
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
Does a triangle have two right angels?
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD
