There are four number of faces in a tetrahedron.
None because a tetrahedron is a triangular based pyramid with 4 faces, 6 edges and 4 vertices

A tetrahedron has 6 vertices that are all nonparallel.Therefore, a tetrahedron has 0 parallel lines.
There are four number of faces in a tetrahedron.
None.
The number 8 has only 2 lines of symmetry; Vertical and Horizontal.
We'll get a n number of vertical angles (pairs)
It has one vertical line of symmetry
7 horizontal lines and 10 vertical lines how many rectangles?

A tetrahedron does not normally have any verticals but it can have three [mutually] vertical edges at one vertex, or two sets of mutually perpendicular edges at two vertices.
100 A rectangle is formed by 2 horizontal lines and 2 vertical lines. There are 5 horizontal and 5 vertical lines so the number of rectangles is 5C2 * 5C2 = 10 * 10 = 100
4 sides, each of which is a isosceles triangle with 3 lines of symmetry, gives 12.
