No because the sum of its shortest sides must be greater than its longest side to form a triangle.

What is the area of a triangle with the side lengths of 2 12 and 18?
These dimensions do not form a triangle.
What is the perimeter of a triangle which sides measure 6 inches?
18 inches and it is an equilateral triangle
Possible rectangles with a perimeter of 18 cm and whole-number lengths of sides?

Can a triangle have sides that are 6 10 and 18?
The definition a triangle is that it has three sides and if it had any more or less it would become another shape. So, no.
What is the perimeter of a triangle whose sides measure 10 cm 15 cm and 18 cm?
Perimeter of a triangle is given by: sum of the three sides =(10+15+18)cm =43cm Done.
Given two sides with lengths 34 and 14, which of the following lengths would NOT work for the third side of a triangle?
18
Can 12 13 and 18 be lengths of the sides of a right angle triangle?
No because they don't comply with Pythagoras' theorem.
Given two sides with lengths 34 and 14 which number would not work for the third side of the triangle?
18
Can 18 24 30 be the side lengths of a right triangle?
YES. 18 and 24 are the two leg lengths and 30 is the hypotenuse then by Pythagoras' Theorem :- 182 + 242 = 302 324 + 576 = 900......which is true and therefore the three side lengths 18, 24 and 30 do form the sides of a right-angled triangle.
What is the area of a triangle with the side lengths of 2 12 and 18?
These dimensions do not form a triangle.
Which sides of lengths below could form a triangle?
To see if three lengths can be made into a triangle:Add together the two shorter lengths;if this sum is greater than the remaining length, then a triangle can be made;otherwise the sum is less than or equal to the remaining length and a triangle cannot be made.examples:3, 4, 53 + 4 = 7 > 5 ⇒ is a triangle 5, 5, 85 + 5 = 10 > 8 ⇒ is a triangle 12, 30, 1812 + 18 = 30 ≤ 30 ⇒ is not a triangle 12, 35, 1812 + 18 = 30 ≤ 35 ⇒ is not a triangle
Can a right triangle have side lengths of 12 14 and 18?
no.
What is the area of an equilateral triangle with side lengths of six?
18
Can you have a triangle with the sides 4 13 and 14?
To check whether it is possible to have a triangle with side lengths 4cm, 13cm, and 14cm, we use a special rule.The rule is: If you take any two sides of a triangle and add their lengths, the sum of the lengths must be greater than the third side.Test this triangle. 4+13=17, which is bigger than 14. 14+4=18, which is bigger than 13. 13+14=27, which is greater than 4.The rule works for all side combinations, so it is possible to have a triangle like this.So the answer is: yes, you can have a triangle of side lengths 4cm, 13cm, 14cm. (Note that the lengths do not have to be in centimeters, for example they can be 4m, 13m, and 14m)
What are the lengths of the missing sides of a 30-60-90 triangle if the longer leg of the triangle is 18 centimeter?
The longest side of the triangle will always be opposite the largest angle, which is 90° in this case. We can use the sine law to work out the other sides with that: sin(90°) / 18 = sin(60°) / x = sin(30°) / y 1/18 = sin(60°) / x x = 18 sin(60°) x = 18√3 / 2 x = 9√3 1/18 = sin(30°) / y y = 18 sin(30°) y = 9 So the triangle has a sides of 9 and 9√3, with a hypotenuse of 18
The perimeter of a rectangle is 36 The ratio of the lengths of the sides is 2 and 7 What are the lengths of the sides?
L + W = P/2 = 18. In ratio of 7:2 sides are 7/9 x 18 and 2/9 x 18 ie 14 and 4
What is the perimeter of a triangle which sides measure 6 inches?
18 inches and it is an equilateral triangle
