The sides of 8 and 9 would have to stretch out straight in line in order to reach the ends of the side of 17,
and then they would flop down right on top of it. The triangle would have two angles of zero degrees,
and one angle of 180 degrees. When you looked at it, it would look like a straight line segment with a
length of 17; you wouldn't know that there were two other line segments lying on top of it.
A mathematician might call that a "degenerate triangle". But in a practical sense, I don't think
anyone else would accept it as a member of the triangle club.

Is it possible to build a triangle with the lengths of 9 8 and 17?
No. Because the total length of the two smaller sides (9 and 8) equal the length of the remaining side (17). No angles would be formed, so there would be no triangle. The total length of the two smallest sides has to be greater than the length of the longest side in order to make a triangle.
What is the length of the hypotenuse of a right triangle where the two sides are 8 units and 15 units long?
17 units in length
What is the perimeter of a triangle when the sides are 15 17 10?
Add all three sides. Perimeter = 15 + 17 + 10 = 42
What is the length of the third side of a triangle when the other sides are 17 cm in length with an angle of 45 degrees between them?
Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.
What is the size of the third side of a triangle when the other sides are both 17 cm in length with an angle of 60 degrees between them?
17 cm because it's an equilateral triangle
