GEO

We use the diagram above where lines l and m are parallel and line t intersecting both l and m is called a transversal. We identify angles by their positions in this diagram. For example, angles 1 and 2 are both facing in the same direction, to the upper right. Such angles are called corresponding angles. Similarly we have angles 3 and 6, angles 4 and 7, and angles 8 and 5 as corresponding angles.

Angles 8 and 2 and angles 3 and 7 are on opposite sides of the transversal and between (interior) the parallel lines. We call these angles alternate interior angles.

Angles 1 and 5 and angles 4 and 6 are on opposite sides of the transversal and above and below (exterior to) the parallel lines. We call these angles alternate exterior angles.

A direct result of the famous Parallel Postulate is that corresponding angles are equal. Accepting this fact gives us these relationships

Using these facts, especially the fact that corresponding angles are equal, we can show that other angles must also be equal.

Since angle 2 is supplementary to angle 6 and angle 1 is supplementary to angle 4, we know that angles 6 and 4 are equal because they are supplementary to equal angles. These angles 6 and 4 are alternate exterior angles.

Since angle 1 is supplementary to angle 3 and angle 7 is supplementary to angle 2 and angles 1 and 2 are equal, we also know that angles 7 and 3 are equal because they are supplementary to equal angles. These angles 7 and 3 are alternate interior angles.

Greek Customs officers on strike

Major fuel shortages are spreading across Greece as customs officers decide to extend their strike against austerity measures until Tuesday.

Long lines of cars are to be seen in petrol stations across greece as fuel is running out after an extension of customs officers industrial action against the neoliberal austerity measures imposed by the government on the pretext of the national credit crisis. Initially the strike which began last Tuesday 16 February was to end on Friday 19, but customs officers have announced its extension to Tuesday 23 causing panic to drivers and a headache to the government. According to the bourgeois media, half the stations in and around Athens have already run out of unleaded, with the depots of the rest expected to empty within the day. The only city that has evaded the problem due to extended deposits is Salonica. Mr Kiousis, the petrol station union president has claimed that already across the country 85% of petrol stations are completely dry.

NASA

This website is great because it shows information about NASA, the space station and the shuttles. It also shows information about the Moon, Mars, Earth, the Solar System and the Universe. It also shows technolgy that helps space exploration and discovery, with the ultimate goal of not only uniting Earth, but uniting, colonizing, and finding intelligent life throughout our solar system.

Google Maps

Maps.google.com

Maps.google.com is a world renown website doing what the website implies. A system run by google, and easily accessible by viewing the google homepage. It's a simple system of maps for practically everything, you just type in the address of the place you're looking for, and google maps will give you a detailed map, and(optionally) possible routes to take to get there, from your current location. I give this a thumbs up because of the simple feel of google maps to veteran users on the web, and those who are still getting the feel of the internet. Also, possibly the best reason to use it, GOOGLE MAPS IS FREE!!!
Borat approves.
