I generally use a pencil and ruler.
To construct the right angle to draw it I also use compasses.
To measure the right angle to draw it I also use a protractor.
a protractor
an L-square, a T-square, or a protractor
Draw a square
Draw a parallelagram this has the opposite sides parallel and no 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
You can't.
First you draw a square. A square has 4 right angles. If you draw a line above one of the right angles and rub out the angle which you have drawn a line above you have a pentagon with 3 right angles.

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
Yes.
Draw them at right angles to each other.
it is not possible
No
You can't.
