Well, there aren't really. The line to the left is the first base line and the line to the right is the 'out of bounds' line. These two lines form the 'restraining box' and when a runner runs to first base they are supposed to stay within this box. If the runner runs outside of the restraining box they can be ruled out for interference should a thrown ball hit them.
The equator and the Greenwich meridian.
Depending upon the base, it will either have no parallel sides or up to (number of sides ÷ 2) sets of 2 parallel lines. The number of angles depends upon the base and is 3 × (base + 1).

First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
A polygon is a 2-dimensional figure bounded by three or more straight lines. Any one of its sides may be considered a base.
Let the second base be x: 0.5*(first base+x)*height = area x = (2*area/height) - first base
It all depends on your drawing, they all need different sets of base lines, as in anime people need base lines to draw the head, the horizontal line is used for the eyes.
the first lines are : my mother drove me to the airport with the windows rolled down. it was seventy-five degrees in Phoenix , the sky perfect, cloudless blue. those are the first 2 lines of the book. :)
Consecutive angles of a parallelogram must be supplementary. The length of the base is irrelevant.

12 faces. The number of parallel lines will depend on whether or not the prism is regular and right. In a regular right prism there are 10 parallel edges along the "length". 10 parallel lines make 45 pairs (1-2, 1-3, 1-4, ... 2-3, 2-4, ... etc). Each line at a base has one parallel line at the same base and two at the opposite base. Each such quartet makes 6 pairs of parallel lines and there are 5 such quartets - so 30 pairs of parallel lines in the bases. That makes a grand total of 75 pairs of parallel lines.
A square and a rectangle have perpendicular and parallel lines. The two side lines extending upwards from the base line are perpendicular to the base line. The line extending from each of the side lines across the top is perpendicular to the side lines. The top line is also parallel to the base line, and the side lines are also parallel to each other.
