a right angle is 90 degrees so its kind of like the side of a square. I you had more than one it would be a square.

Btw thats a really easy question.

A right triangle cant have 2 right angles because all the angles in a triangle add up to 180 degress. And a right triangle is 90 degrees. SO.......
if there were 2 right angles, you would have 90+90 which is already 180 degrees. But in a triangle you need 3 angles, and for obvious reasons, you cant have a 0 degree angle!
Hope this help. Try to draw a picture too.. It won't work out.

The sum of the three angles of a triangle always equals exactly 180 degrees. So if two of the angles are 90 degrees each, the 3rd angle would be 0. Thus there would be no triangle.

Three angles of a triangle add to exactly 180 degrees. A right angle is 90 degrees, so you would only have two angles which is not a triangle. Also, try drawing it and it will just look like the beginning of a square.

Triangles are by definition shapes that all interior angles add to 180 degrees. (a+b+c=180 degrees)

Right angles are by definition 90 degree angles.

So if you have two right angles (let a and b = 90 degrees)

90+90+c=180, there can be no value for C, thus you are left with a straight line!

the key is you have to remember that the sum of the interior angles of a triangle is 180.
if there are two right angles that equals 180 and there are no degrees left for a third angle..
if that is confusing, then draw it. if you draw two right angles you will realize that in order to close in the figure you would have to draw a fourth line.

It can't have 2 right angles. because the total degrees would sum to 180 and you would not have 3 vertexes.
