How to calculate the hypotenuse of triangle

How to calculate the hypotenuse of a triangle is as follows:

Clearly defined.

The hypotenuse of a right triangle refers to the opposite side of the right triangle and the longest side of the right triangle. The sum of the included angles formed by the hypotenuse and the other two sides of a right triangle is 90 degrees.

Clear formula.

Pythagorean theorem is the most widely used method to find the side length of a straight triangle. Answer? +b？ =c？ , where a and b are the right sides of a right triangle and c is the hypotenuse.

Define the solution conditions.

According to Pythagorean theorem, for an ordinary right triangle, when any angle other than the right angle is unknown, the hypotenuse is needed, and only when the lengths of two right angles A and B are known can it be calculated.

Clear the calculation process.

According to the formula, it can be converted that the length of hypotenuse C is the sum of the squares of two right angles and then the root sign is opened.

In geometry, the hypotenuse is the longest side of a right triangle, opposite to a right angle. The hypotenuse length of a right triangle can be obtained by Pythagorean theorem, which means that the square of hypotenuse length is equal to the sum of the squares of the other two sides. ?

For example, if the length of one side is 3 (square, 9) and the length of the other side is 4 (square, 16), then their squares add up to 25. The length of the hypotenuse is square root 25, which is 5.

Simple calculation of special cases.

If it is an isosceles right triangle, then the length of the hypotenuse = the length of the right multiplied by the root number 2; If there is an included angle of 30, the length of the hypotenuse is twice the length of the right-angled side corresponding to the angle of 30.

The calculation of Pythagorean theorem is a bit complicated. Novices should master the calculation process and calculate carefully to avoid mistakes.
