1. In a right triangle, the length of the hypotenuse (also called hypotenuse or opposite side) is the longest side in the right triangle. The formula for finding the length of hypotenuse needs to know the length of two right-angled sides, that is, the length of two adjacent sides of right-angled triangle. We can use Pythagorean theorem to solve the length of hypotenuse, and the formula is c = (A 2+B 2) 0.5.
2.a and B are the lengths of two right angles of a right triangle, and C is the length of the hypotenuse. This formula is based on the variation of Pythagorean theorem, that is, the sum of the squares of two right-angled sides of any right-angled triangle is equal to the square of the hypotenuse. When this equation is squared, the formula for solving the length of hypotenuse is obtained. It only applies to right-angled triangles, because only in this case does Pythagorean theorem hold. Non-right triangle is not applicable.
3. For example, suppose you have a right triangle, in which one side is 3 and the other side is 4. The above formula can be used to solve the problem that the length of the hypotenuse is c = (3 2+4 2) 0.5 = (9+16) 0.5 = 5. So the hypotenuse length of this right triangle is 5.
Methods of learning mathematics
1. Make a plan and pay attention to basic knowledge: make a reasonable study plan, including daily study tasks and time schedule. This can help you manage your time better and master your study progress. Mathematics is a basic subject. To learn mathematics well, we must first master the basic knowledge. Therefore, when learning mathematics, we should pay attention to the study and mastery of basic knowledge, such as mathematical formulas, theorems and laws.
2. Lots of practice and independent thinking: Mathematics is a subject that needs a lot of practice. Through a lot of practice, we can deepen our understanding and mastery of knowledge points and improve our problem-solving ability and thinking level. Learning mathematics requires independent thinking. Through independent thinking, you can cultivate your own mathematical thinking ability and problem-solving ability.
3. Ask for help, set the wrong book: In the process of learning mathematics, if you encounter difficulties, you should dare to ask for help. You can ask teachers, classmates or online math learning forums for help to solve problems. Establishing the wrong questions can help you better summarize your learning situation, find your own shortcomings and make up for them in a targeted way.
