It can be a square or a rectangle
A sphere- there are no faces, edges or vertices
A trapezium is a quadrilateral and so has four sides and four vertices.
an isosceles triangle
Any shape with two or more vertices can have one or more pairs of equal angles. The simplest of these is a symmetric lenticular shape with just two vertices.
The shape that has no vertices and is round is a circle. The circle is the only shape that does not have vertices.
A sphere- there are no faces, edges or vertices
Yes, the Platonic solids (excluding the sphere which does not have vertices).
A cube
Yes, a prism has an even number of vertices. A prism is a three-dimensional shape with two parallel and congruent polygonal bases connected by rectangular or parallelogram faces. The number of vertices in a prism is equal to the number of vertices in its bases plus the number of vertices in the lateral faces. Since each base has an equal number of vertices, and the lateral faces have an even number of vertices, the total number of vertices in a prism is always even.

4 sides, 4 vertices, 2 equal angles, 2 pairs of equal sides
If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
No. The sides of a shape don't need to be equal in length to be parallel.
The semi circle is a shape which has 1 line of symmetry 1straight side 0 equal length sides 0 parallel sides 2 vertices 0 diagnals
