In southern Africa, the mornings can be pretty chilly, but the afternoons can be quite hot. You won't have a chance to run back to your hotel and change, so dressing in layers at the start of your day will help keep you comfortable. Even if you're not going on safari during the rainy season, you might still be caught in a downpour. The jacket doesn't need to be heavy, just waterproof, and it should match the rest of your wardrobe so that it blends in to your surroundings. The weather in central and east Africa tends to be more temperate throughout the year, but it can be very chilly in the morning. Convertible pants - where the bottom half of the bottoms zip off to make shorts - are your best bet for a safari there. In South Africa, the rainy season coincides with the hottest weather. So while you'll want to pack a rain jacket and waterproof hats and shoes, you should also make sure your shirts and pants are lightweight and breathable to keep you cool. The rainy season in Eastern Africa coincides with the area's coolest weather. Long pants and a lightweight long-sleeve shirt are great options to wear under your rain jacket.

Summary: Dress in layers in southern Africa. Pack a rain jacket if you're going to eastern Africa. Pick convertible pants for safaris in central and east Africa. Prepare for rainy, hot weather in South Africa. Be ready for rainy, cool weather in eastern Africa.

Buy the strips that identify chlorine, alkaline, pH, and cyanuric acid. Nowadays, you don't have to bother with different tests for different chemicals. Move to an area that's separated from the pool's skimmer, and dip the test strip about 18 inches (46cm) into the water for about ten seconds. Match the color readings to the color description on the product box or bottle. Make sure to read the product's instructions carefully, as different manufacturers might have different procedures. It's very important to adjust your water in case your readings do not match the recommended ranges. Using the right chemicals will easily adjust the ranges should they not meet suggested standards.

Summary: Purchase testing strips from your local pool store. Dip the test strip into the pool. Wait until the different colors fill in. Make sure that your readings fall in the appropriate range.

. Accurately using and understanding words will give people the impression that you are intelligent and thoughtful. You can improve your vocabulary through reading, playing word games like Scrabble and Boggle, and by looking up words you don't know in the dictionary. You might want to carry a pen and pad of paper with you so you can write down words you hear that you don't know to look up later. If you have a cellphone, you can write yourself a note or send yourself a text so you don't forget to investigate words later. It's easy to feel self-conscious when someone uses a word you don't know, but you shouldn't be afraid to ask questions. Asking someone you're speaking with what a word means is a quick, direct way of learning new words. . Sometimes, people just want to be heard. Even if you don't agree with someone or don't completely understand what is being said, saying, "I hear you," can be an impressive mark of maturity. You might want to explain yourself further when recognizing others' opinions. For example, you might say, "I hear what you're saying, and I think you have a good point, but I disagree with you for these reasons..." . This can be difficult for both kids and adults, but if you are able to take a step back and admit when you are wrong, other people will think you are mature. Finding out you're wrong about something also gives you a chance to change for the better, and telling people you were wrong may win you their admiration. If you find that you're having a difficult time admitting you're wrong, try positively coaching yourself through those feelings. You might tell yourself, "It's OK to be wrong. People are wrong all the time. I made a mistake, it's no big deal." When you're having a conversation, it's not uncommon to say something you don't mean. This can cause misunderstandings and arguments. When speaking, don't be afraid to take a second to collect your thoughts and choose the right words to express yourself. When the right word is on the tip of your tongue, you can ask others for help. You might say, "I'm drawing a blank. The word I'm looking for starts with a 't.' Can you help me think of it?" In some situations, there might not be a word that perfectly captures how you feel. When this happens, you might describe the feeling and follow up by asking, "Have you ever felt that way?"

Summary: Improve your vocabulary Recognize the opinions of others Admit when you are wrong Choose your words carefully.

When a triangle has two sides that are in the same proportion to another triangle and their included angle is equal, these triangles are similar. Be careful not to confuse this theorem with the Side-Angle-Side theorem for congruence. For congruence, the two sides with their included angle must be identical; for similarity, the proportions of the sides must be same and the angle must be identical. For example: Triangle ABC and DEF are similar is angle A = angle D and AB/DE = AC/DF. Using a ruler, measure two sides of triangle ABC and label them with that measure. Make sure triangle DEF is oriented in the same direction and measure the same two sides. Label these sides as well. Example: Measures of triangle ABC; side AB = 4 cm and side AC = 8 cm. Measures of triangle DEF; side DE = 2 cm and side DF = 4 cm. Using a protractor, measure the included angle, or, the angle between the two sides that you already measured. For this theorem, the measure of the angle should be identical in both triangles. Example: Angle A in triangle ABC is 26. Angle D in triangle DEF is also 26. To use the SAS theorem, the sides of the triangles must be proportional to each other. To calculate this, simply use the formula AB/DE = AC/DF. Example: AB/DE = AC/DF; 4/2 = 8/4; 2 = 2. The proportions of the two triangles are equal. Once you have determined that the proportions of two sides of a triangle and their included angle are equal, you can use the SAS theorem in your proof. Example: Because AB/DE = AC/DF and angle A = angle D, triangle ABC is similar to triangle DEF. Note: If angle A did not equal angle D, the triangles would not be similar. Also, if the proportions were not equal, the triangles would not be similar.
Summary: Define the Side-Angle-Side (SAS) Theorem for similarity. Measure the same two sides of each triangles. Identify the measure of the angle between those two sides. Calculate the proportion of the side lengths between the two triangles. Apply the Side-Angle-Side Theorem to prove similarity.
