I believe that it's not called anything, it is just a symbol to indicate that the angle is a right angle (90 degrees)
A standard diamond shaped kite may not have a right-angle, but kites come in many sizes and shapes. For example, a box kite will have several right-angles. Whereas the rather fancy dragon and animal shaped kites on public display are usually right-angle free.
A squashed open box? Alternatively, a right-angle trapezium: ............................ .-------------....... .|..................\...... .|...................\..... .|....................\.... .|......................\.. .-----------------. ............................
In a right triangle (where one angle is 90 degrees) if the length of the sides are A, B, and C, and the sides A and B form the right angle (90 degrees) then A2 + B2 = C2.
the corner of any building The corner of a shoe box, a brick, a square item
I think it is just called the right angle symbol
A box of some sort, or a door
It has usually a red box at the vertex and is called a "right angle."

One of its interior will be 90 degrees. also there will be a little box in the corner to show that it is a right angle.

Flip the box over to right side up.
An obtuse angle
