Sometimes the task in geometry seems so difficult that it is unclear from what party to it to be risen. Begin with the accurate drawing, and a part of a task will become clearer.
It is required to you
- Pencil, ruler, compasses, knowledge of theorems and rules
Instruction
1. Success of the solution of a task in geometry for 60% depends on competently represented drawing. Attentively read a condition, make sure that you understood it. Now begin to draw the drawing. You do not crush, on the drawing points, letters, lines, figures should not merge. Never draw by hand, surely use drawing accessories.
2. Apply all data about which it is told in a condition on the drawing. Especially allocate what needs to be found. If it is necessary to find not a piece, but abstract size (for example, diameter), then write out required under a condition.
3. Is there is a need, break a task into several stages, that is a number of small subtasks. The solution of each such subtask will be one step away to bring closer you to the solution of all task. Having received the answer, carry out an inspection – whether your answer is right? If you solve a problem from the school textbook, then the correct answer, as a rule, is specified at the end of the textbook. Be verified with it, but if the way of the decision is not known to you, do not try "to adjust" a task to the specified answer.
