wich shaps have right angles
Opposite angles do not bisect any shapes.
No. For example a parallelogram does not have any right angles. The internal angles of all four sided shapes will always equal 360 degrees, but do not necessarily have to include right angles.
Any and all squares and rectangles. Every one of these two shapes has only right angles. Though some triangles also have right angles.

Most shapes have no right angles. Circle, pentagon, hexagon etc. Ones that do include the square and some triangles.
A square shape for example has 4 right angles and a right angle is 90 degrees.
Triangles
Any and all squares and rectangles. Every one of these two shapes has only right angles. Though some triangles also have right angles.
right triangle square rectangle
The diagonals of a square and a rhombus cross at right angles.
Amongst polygonal shapes, only an acute triangle can have all its angles less than 90 degrees. Any other polygon must have one or more right or obtuse angles.
Shapes that do not have right angles include circles, ovals, and various types of polygons such as triangles (specifically acute and obtuse triangles), and irregular polygons. Additionally, shapes like ellipses and curves, such as parabolas, also lack right angles. These shapes can have angles of varying degrees, but none equal to 90 degrees.
