The plane upon which the Earth travels round the Sun is called the ecliptic.
It is only when two bodies are on this plane, and in line with the Sun, that an eclipse is observed. Hence the name ecliptic.
The Earth's spin axis is always oriented about 23.4 degrees from the ecliptic plane.
The Earth's spin axis is never perpendicular to the Sun's rays.
You may be referring to the Sun being directly overhead at the Equator twice per year.

NoIf the slope of a given line is x, than the slope of the line perpendicular to the first line is 1/-x. So if the first slope is negative, the second will be positive, and vice versa.

The first geometric shape that comes to mind with no perpendicular sides is a triangle.

The first procedure-oriented programming language is considered to be Fortran (short for Formula Translation). It was developed by IBM in the 1950s for scientific and engineering computations.
TRUE:: The first two lines lie in the same plain, but are perpendicular to each other. The third line passes through the plane of the first two lines so it is also perpendicular. Think 3-dimension. !!!!!

If the rungs are perpendicular to one side of the ladder, then they must be parallel to the other side of the ladder. This is because if one side is perpendicular to the rungs, the other side, being parallel to the first side, will also be perpendicular to the rungs.
The first C in the 5 Cs of pricing is Company Objectives. It is determined by what the goals of the company are. They could be profit-oriented, sales-oriented, competitor-oriented or customer-oriented. A company can also use a combination of these strategies.

Lines that always form right angles when they meet are perpendicular lines. The first line is perpendicular to a second line.
