Because a right angle is 90 degrees and perpendicular lines meet at right angles as for example as in the capital letter L
No
Yes!
yes it is possible to do that.
No it is not possible to draw 1 triangle with 2 right angles because the angles in a triangle should equal to 180 degrees
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
No, it is impossible to draw an equiangular right triangle. An equiangular triangle has three 60o angles. A right triangle has one 90o angle, and two 45o angles.
no it isnt
Yes!!
No
Yes. The other two angles will be 45 degrees.
No, it is not.
It is possible.
