Summarize the following:
Make sure the needle stays on the endpoint, and that you do not adjust the compass setting. The length of the arcs does not matter. Make sure you do not change the compass setting. Make sure the needle stays on the endpoint, and that you do not adjust the compass setting. The two sets of arcs you've drawn should intersect. To do this, place your straightedge on the point where the arcs above the line intersect, and align it with the point where the arcs below the line intersect. The line you draw between the two arc intersections bisects the line at a ninety degree angle. You have used the compass to outline two congruent circles centered over either endpoint. The intersecting arcs represent the endpoint of a radii from the center of either circle. The length of the radii will be the same, since the circles are the same size.

summary: Draw an arc above and below the line segment. Reposition the compass on the other endpoint. Draw another set of arcs, above and below the line segment. Connect the arc intersections. Draw your perpendicular bisector. Understand why this works.

Summarize the following:
You'll have to play around a bit to figure out what feels comfortable for the story you're writing. Different styles can include past and present tense, first and third person, prose and verse. It will depend on the voice of your characters and what you are trying to express. Try taking your first chapter and re-writing it in different styles until you hit the one that fits best. However, don't be afraid to put your book aside for a few days, as doing this is better than you hating the chore of writing. Writing a book is going to take you a long time and a lot of hard work. When you get stuck, and hit writer's block, don't freak out. There are about a hundred different ways to, and the most practiced is just to wait it out. It'll pass. Every writer has a different way of getting through a novel, so nobody can really tell you the best way to go about it. Some write straight from beginning to end, and others skip around; some write a chapter a day, and others write only when the inspiration hits; there is really no definitive way to arrive at the end of your novel. But in the end, if you give it time, and if you have the passion, you will get there. If it's hard for you to write in sequential order, and you're more interested in one part and then another the next day, then write in pieces. Hopefully, you will know your plot well enough to be able to work in pieces and then go back and stitch those pieces together. Writing in sequential order can get boring, so write what interests you that day. Even if it's another idea, it will all come together eventually. However, there is the danger of getting lazy and not wanting to go back and fill in the parts that are more boring to write. Don't get to that spot, fellow teen writer if even you aren't interested in a certain part of your book, what makes you think readers will be? Take your time. If you reach a point in the novel where you are stuck, take a break and come back to it later. Frustration will be your only reward if you just sit there struggling and trying to do something you can't. A good book or series takes time to make. J.K Rowling and her books (Harry Potter) took her over 17 years to complete. Take your time and in the long run it will be worth it. Don't stay up late, all night, trying to get the whole thing finished in a month. It's doubtful that's going to happen and it will only make you really tired. This, in turn, will make it harder for you to think and work on what you have. Get enough sleep, eat breakfast, do well in school, etc. You will get it finished; even if it takes a year, you will get it finished if you work on it. Rushing through things isn't going to improve your writing, if anything it's going to make it worse. Your first critic is yourself; you will need to go back over everything you have written and revise it to make it better. Especially if this is your first novel, you will have a lot to fix. It's hard to let go, but sometimes even good writing needs to be deleted to move the story in the right direction. There might be huge changes that need to be made before you get to the next step. Get a few friends or family members to read it and give you direction, and then you may want a professional literary editor. You can find one online, even in the phone book, and they can be really helpful. However, they can also be expensive, so if you're confident, you can skip the pro editor. Besides, you should know that your publisher will probably want their own editor to look at it before it's published, anyway. Still, you should at least send it to a teacher or another adult with literary experience that you trust. Teens and friends, though helpful, will miss things that teachers and other adults will pick up their first time through, and / or will be gentle to spare your feelings. Do not be afraid of criticism, as sometimes it's downright embarrassing, but most of the time it really helps you to grow as a writer.
summary: Find your writing style. Try to write a little every day. Go gradually. Edit and revise your first draft. Get outside editing help.
