It depends on which type of cuboid we are talking about. If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry. If it is a cuboid with length, width and height all different, then it has three planes of symmetry. If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.

There are infinitely many lines of symmetry. Every line can be a line of symmetry for a suitable shape.

It depends what type of triange it is. If it is an equilateral triangle, you can draw 3 lines of symmetry If it is an isosceles triangle, you can draw 1 line of symmetry If it is a scalene triangle, you cannot draw any lines of symmetry
it has 5 planes of symmetry
A nephroid has 2 lines of symmetry.
