Since Yahoo is experiencincing annother problem and thumbs-up aren't possible at the moment: Jason is right! That's the only way - although with his solution you do not only have two, but 4 right angles...

You can't. It is impossible to draw a triangle with two 90° angles.
However, take the equator. If one was to use this as the base of a triangle and draw two lines originating at the north pole, and following the lines of 0° and 90° longitude, respectively, until they reached the equator, one would achieve a triangle with three 90° angles (stand on the equator at 0° latitude [GMT]. Walk to the north pole, turn 90° clockwise, walk down until you hit the equator, turn 90° clockwise and walk along the equator to your starting point). Others may argue that it is not a triangle as the curvature of the Earth disrupts this, but, if one was to walk the lines, they would appear straight and with three angles, thus a triangle.
I hope you understand!
If one was to draw a triangle on a saddle-like surface, the angles would equal less than 180°.

You cannot construct a triangle with 2 interior angles equal to 90 degrees. The sum if the interior angles of a triangle is 180 degrees. Your shape would have a base and the other two sides would be parallel. Parallel lines never meet so you can never form a closed three sided shape i.e. a triangle. It could have been a trick question if you had asked '....from two right angles.' Then take a square and fold it along one of the diagonals. The diagonal fold bisects two of the square's right angles. The folded shape is an isosceles right angle triangle with interior angles of 90, 45 and 45 degrees.

Impossible. Mathematically, the sum of angles of any triangle is two right angles but if one angle is 90 degrees then the sum of two remaining angles must also be 90 degrees.

Also, there should always be three angles to make a triangle.

Hope this helps.

A triangle with two right angles is by necessity an isoceles triangle (since it has two equal angles) but either one vertex is infinitely far away (at the intersection of your parallel sides) or your base is no longer than a point, in which case the sides coincide, and you can put the opposite vertex as far as you want away from the base. Either way, it doesn't look much like a triangle.

It is impossible... a triangles three angles must add up to 180 - if two angles are 90 degrees, then the third cannot exist - therefore - not a triangle!

Draw it on a sphere. For example, put two vertices on the Equator and one at the North Pole. You can even have three right angles that way.

The rule that the sum on the angles is exactly pi radians/180 degrees is pretty much the definition of a "flat" as opposed to "curved" surface or space.

Edit: tjs -- The bear could also have been near the South Pole. Think about it. :)

"how do you make a triangle with two right angles?"

You think outside the box and you draw it on a sphere - you can even draw one with 3 right angles!

You can't.

The sum of all the angles in a triangle must = 180 degrees

Two right angles = 180 degress therefore none left for the third angle.

So it's impossible.

its impossible a triagle has to have its angles add up to 180 degrees and 2 right angles is already 180 degrees so there is no way u can have a third angle and therefore no triangle.
