yes, it is very possible
===================
No, it is impossible.
The sides with lengths of 3 and 4 can't open far enough
to connect to the ends of the side with length 8.
No
yes
Yes
The last side length could be between 4 units and 10 units inclusive.
How about 3, 4 and 5 or 6, 8 and 10 in fact any of a Pythagorean triplets will are possible.
No, it is not.
No
No.
yes
Yes
True and it will be an equilateral triangle
Yes
true
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
true
If its a right angle triangle then its side lengths could be 3, 4 and 5
yes it is. When you're dealing with the Pythagorean theory, a 3,4,5 triangle is a special triangle. For example, if a triangle has side lengths of 3cm and 4cm, then you automatically know that the other side length is 5cm. It also works if the side lengths are 5cm and 4cm or 5cm and 3cm.
