Because the sum of the smaller sides is greater than the largest side and it is possible to construct one right angle triangle with the given lengths
No.
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.
A scalene triangle has three sides of different lengths. A right triangle can be scalene - for instance the '3-4-5' triangle has a right angle opposite the side which is 5 units long.
Yes.
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
If you mean lengths 2, 3 and 5 then the answer is no because in order to construct a triangle the sum of its 2 smallest sides must be greater than its longest side
Because the sum of the shortest sides is less than the longest side and in order to construct a triangle the sum of its shortest sides must be greater than its longest side.
If its a right angle triangle then its side lengths could be 3, 4 and 5
Because all side lengths are different, it must be a scalene triangle.
Yes, an isosceles triangle with two size lengths of 3 and one of 8 :)
Because the sum of the smaller sides is greater than the largest side and it is possible to construct one right angle triangle with the given lengths
No, it is not.
An acute triangle sometimes known as a scalene triangle has 3 different side lengths and 3 different interior acute angles that add up to 180 degrees
Add all 3 side lengths.
No
True and it will be an equilateral triangle
