yes you can
There are 4 angles in a trapezoid that add up to 360 degrees.
it is a trapozoid
no
Yes.

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, but the 4 interior angles of a trapezoid must add up to 360 degrees.
if i put three points on the common arm ,then they are common points for both the two angles
No, because then it would be a rectangle.
The sum of all four angles is 360 degrees. If three of the angles were right angles then the fourth would have to be a right angle. You would then have a rectangle or a square, but not a trapezium.
Yes.
To draw a six-sided shape (hexagon) with three right angles, start by creating a rectangle that will form the base. From one of the shorter sides, draw two vertical lines that extend outward at right angles, creating two additional sides. Connect these lines back to form a hexagon, ensuring that two of the angles remain right angles while adjusting the other angles as needed to maintain the six-sided structure. The final shape will have three right angles and three other angles that complete the hexagon.
