INPUT ARTICLE: Article: Latitude is a measure of distance north or south of the equator, which is an imaginary horizontal line around the exact mid-point of the earth between the 2 poles. The earth is divided up into 180 latitude lines on either side of the equator, called parallels. These parallels run horizontally around the earth, parallel to the equator. 90 of them are north of the equator, while the other 90 are south of it. Longitude is a measure of distance east or west of an imaginary vertical line that runs down the center of the globe from the North Pole to the South Pole, called the prime meridian. Longitude lines are a series of vertical lines from North Pole to the South Pole, also called meridians because every place touched by the same meridian have midday at the same time. There are 360 meridians on either side of the prime meridian, with 180 of them located east of the prime meridian, and the other 180 located to the west of it. The meridian on the opposite side of the earth from the prime meridian is called the anti-meridian. The measurements of latitude and longitude are usually expressed in degrees (°), minutes (′), or seconds (″). The entire distance from one parallel to another or one meridian to another is 1°. To produce even more accurate measurements, each degree can be further divided up into 60 minutes, and each minute into 60 seconds (for a total of 3,600 seconds per degree). Latitude and longitude are measured in degrees rather than absolute units of measurement (such as miles or kilometers) because the Earth is spherical. While the distance between degrees of latitude is constant (60 nautical miles or 111.12 km), the Earth’s shape causes the distance between degrees of longitude to decrease as you approach the poles. When measuring latitude in either direction, the equator is considered the starting point, at 0° latitude. Likewise, the prime meridian is the starting point for measures of longitude, representing 0° longitude. Every measure of latitude or longitude is expressed in terms of how far it is from the origin point in either direction.  For example, the North Pole is at 90°N, meaning it is 90° north of the equator. The antimeridian is at 180° either east or west from the prime meridian. The Great Sphinx of Giza in Egypt is located at 29°58′31″N, 31°8′15″E. This means it is just under 30° north of the equator in latitude, and about 31° east of the prime meridian in longitude.

SUMMARY: Get familiar with the concept of latitude. Learn the definition of longitude. Examine the units of measurement used for latitude and longitude. Measure latitude and longitude relative to the 0 point.


INPUT ARTICLE: Article: Boxed dyes are more drying than professional dyes, so they will increase the damage on your hair. Not only that, but the compounding of color can make it hard to predict the results. Once you’ve added the boxed dye, it will be hard for anyone to fix your hair color if you don’t like the results. Your stylist may be able to gently change the color by applying a toner rather than re-dying it, so talk to them before you try anything drastic. If you’ve already tried to re-dye your hair once and don’t like the result, don’t try another home dye job. This could damage your hair, and the color won’t come out right since you already have two dyes on your hair. Provide your stylist with a complete hair history so that they can give you good advice on how to proceed. If you don’t tell your stylist that you’ve already used dye, your hair may not come out as expected. Trust your stylist to help you make the best choice to keep your hair healthy.  Tell them how many times you’ve dyed your hair, as well as how often. Say, “I’ve already used two different box dyes. I put the first one on three weeks ago, and last week I tried to fix the color.” Explain what you don’t like about your current color so that they can help fix the issue you’re having. Say, “I don’t like how brassy my hair looks.”

SUMMARY: Avoid using boxed hair dye over a professional dye job. See a stylist if you’ve already tried to re-dye your hair once. Tell your stylist that you’ve already colored your hair.


INPUT ARTICLE: Article: Measure its length. In this case, the stick measured 10.5cm/4.3".

SUMMARY: Place one of the popsicle sticks on a sheet of paper. Construct an equilateral triangle based on the length of the popsicle stick.


INPUT ARTICLE: Article: If your teen is abusing steroids, there will most likely be signs. Side-effects are common, so it's important to pick up on these symptoms so that you can properly intervene. When you know the symptoms of steroid use, you can address them with your teen and with their physician. Some common symptoms include:  Fluid retention (puffiness in the face) Sudden and severe acne Sudden weight gain Hair loss Jaundice(yellowing skin and eyes) Bleeding (usually in the nose) Facial hair (for girls) Breast growth (for boys) Changes in mood are often the first signs of steroid use. Steroids can cause extreme changes in mood and aggression, sometimes called “roid rage.” Long-term use of steroids can lead to more aggression and extreme mood swings. Notice if your teen has experienced sudden changes in mood or aggression. Let them know you're concerned about their well-being.  Say, “I've noticed your mood is different, and you seem a lot angrier than before. Can you tell me what's going on?” Sometimes, teens experience mood changes that are connected to their mental health. If you're concerned about your teen's mood and it might not be related to steroids, see a therapist. If your teen is addicted to steroids, they will likely need some kind of step-down program. Suddenly stopping use can cause harm to the body. Some symptoms include  cravings, fatigue, depression, restlessness, decreased appetite, problems sleeping, and headaches. Your teen may need to attend a program or rehabilitation facility to come off of the steroids. Steroids can increase mood swings and even increase suicidal thoughts or behavior. Watch out for any signs that your teen is considering suicide. If you suspect your teen is suicidal, take it seriously. Get help immediately, such as taking your teen to the emergency department. Call emergency services to get help and know what to do.

SUMMARY:
Monitor physical symptoms. Watch for mood changes. Address withdrawal symptoms. Look out for suicidal behavior.
