What shape has three right angles?
I will rephrase your question as "What shape has only three right angles?" A shape is a 2D drawing that encloses some space. The sum of the angles must exceed 270 degrees. A rectangle is out of the question as it has four right angles. But a 5 sided shape with unequal sides (irregular pentagon) or higher number of sides is fine. I wish Wikipedia would let draw on these answers, because I could draw hundreds of shapes with three right angles. When we talk of shapes, the most regular shapes come to mind, triangles, squares, pentagons, etc. But you did not spcify that my shape had to have straight sides. Imagine, for example, a circle which I will break at three places and insert right angles. Weird, but it does have three right angles. Do the right angles have to face in towards the center? I could even draw a more bizarre shape with with three right angles facing out, connected by curved lines.
What 2d shape has 1 right angle and 3 sides are straight?
triangle
Degree of freedom for a truss?
Number all the structural degrees of freedom in your truss. In a 2D (planar) truss, each joint can have a maximum of two degrees of freedom: one in the global X-direction and one in the global Y -direction. If a degree of freedom is restrained by a reaction, then it doesn't get a number.
Does a line graph show the relationship between three variables?
a simple 2d xy line graph has only the possibility for 2 different variables (x and y). for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs.

What are the similarities for a hexagon with equal sides and a square?
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
A 2D shape with 2 right angles and the other angles not right angles?
