There are 180 degrees total in a triangle. A right angle is 90 degrees, so two would already reach 180. (90+90=180) You need three angles to make a triangle, so if there are already 180 degrees, you can't have a third angle.

It is impossible to have a triangle with two right angles. This is because a triangle=180 degrees. Two right angles would make up all of the 180 degrees.
NO, in order for a triangle to have two right angles, it would also have to have two parallel sides. This is impossible, as these two side would stretch into infinity and never close the triangele
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
An obtuse triangle can have no right angles, and has two equal angles.
No, because two right angles=180 degrees. A triangle has three sides and is 180 degrees, so two right angles would not form a triangle.
