If the length of the third stick is even, how to make it () species?

If the length of the third stick is even, how to make it () species?


Even numbers with the length of the third side between 0 and 10 are 2, 4, 6 and 8



The lengths of the two sticks are 3cm and 5cm respectively. The third stick should be selected and nailed into a triangle. If the third stick is even in length, the third stick should be selected
The lengths of the two sticks are 3cm and 5cm respectively. The third stick should be selected and nailed into a triangle. If the length of the third stick is even, what is the length of the third stick?
Let the length of the third stick be xcm|


Three sides of triangle must satisfy
The absolute value of the difference between the two sides is less than that of the third side,
The sum of two sides is greater than the third
Because the negative number is less than the positive number, so take the absolute value
For example, 4, 8, 5
Negative numbers are meaningless when evaluated in triangles
So take the absolute value



How many sticks can be drawn randomly into a triangle with a length of 1cm 2cm 3cm 4cm 5cm 6cm?


One centimeter is useless. Just ignore it,
What's more, it can't be encircled: 235 246
Then it can be divided into: 234 245 256 345 356 456 six
The rule is: if the three sides are ABC, then a + B is greater than C
