There are many lengths that can be used to make triangles. Basically take the longest side, add the two shorter sides together, it can be a triangle as long as the 2 shorter sides added together are longer than the longest side.

Can the set of lengths be the side lengths of a right triangle 7ft 12ft 17ft?

No because the given sides do not comply with Pythagoras' theorem for a right angle triangle.

How do you find a separate set of lengths for a similar triangle?

just use a scale factor! multiply all the dimensions by X and you'll have the dimensions of the new triangle. of course the angles and all are the same b.c theyre similar.

Would the following set of sides build a triangle 4 4 5?

Yes. If the sum of the length of the two smaller sides are greater than the length of the larger side and none of the lengths of any of the sides equals 0, then it is a triangle. It is not, however, an equilateral triangle or right triangle (that would be 5, 4, 3), though it is an isosceles triangle.

Does a right triangle only have one set of perpendicular lines?

Yes, a right triangle has only one set of perpendicular lines.

What is the usual shape of a set square?

triangle

They are Pythagorean triples

How many examples are in a triangle shapes set?

Infinitely many. The smallest side of a triangle can have infinitely many possible lengths.

Which shape has 1 set of parallel lines?

It is a trapezoid that has one set of opposite parallel lines of different lengths.

Which set of side lengths will not form a right triangle?

Plug the side lengths into the Pythagorean theorem in place of a and b. If a2 + b2 = c2, it's a right triangle. C needs to be an integer, so c2 will be a perfect square.

Which set of numbers can not represent the lengths of the sides of a triangle?

There are lots of sets of numbers that fit that definition! But the important thing to remember about triangles is the Third Side Rule, or the Triangle Inequality, which states: the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides. So you can have a triangle with sides of 3, 4 and 5 because 3 < 4 + 5, 4 < 3 + 5 and 5 < 3 + 4; and because 3 > 5 - 4, 4 > 5 - 3 and 5 > 4 - 3. But you can't have a triangle with sides 1, 2 and 8, for example. Just imagine three pieces of wood or three straws with lengths 1, 2 and 8. Put the longest piece, 8, horizontally on the table. Then put the other two, one at each end of the longest piece. Could those two shorter sides ever meet to form a triangle? No, never!-----------------------------------------------------------------------------------------------------------The length is always positive, so that all real positive numbers can represent the length of sides of a triangle: {x| x > 0}.------------------------------------------------------------------------------------------------------------Whoever added that to my answer, sorry, I beg to differ! The question asked what SET of numbers cannot represent the lengths of the sides of a triangle. There are infinite possibilities for that. While the lengths are always a set of real positive numbers, not every possible set of real positive numbers is a potential set of numbers that represent the lengths of the sides of a triangle!

What relationship does the mid segment have to the base of a triangle?

A trapezoid midsegment is parallel to the set of parallel lines in a trapezoid and is equal to the average of the lengths of the bases
