Can a right triangle have side lengths of 12 14 and 18?
no.
What is the area of a triangle that is 12 in and 16 in?
What is 12 in ? And what is 16 in ? ? Are they the lengths of two sides of the triangle ? Are they the length of one side and the height of the triangle ? The area of any triangle is 1/2 of the product of (length of its base) x (its height).
Do the side lengths 9 15 and 12 form a right triangle?
Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.
A triangle has two sides of lengths 4 and 15. What value could the length of the third side be Check all that apply.?
It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.
How do you find the missing side of a congruent triangle?
Proportions would be the best way; given the sides of the triangle, use ratios to find the corresponding side on the congruent triangle. For example: if three sides are given, 3, 4, and 5, and you had to solve a triangle with lengths 9, 12, and x, this is how you would do it. Given the triangles are congruent, 4/5 = 12/x 4x = 60 x = 15
Can a right triangle have side lengths of 12 14 and 18?
no.
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 length of a side of an equilateral triangle that has a altitude of 12?
Given an altitude of 12 units, an equilateral triangle has side lengths of 13.9 (13.85641) units.
Can a triangle with side lengths 9 feet 12 feet and 15 feet be a right triangle?
Yes.
What kind of triangle is one with side lengths of 5 12 and 13?
A right-angled triangle. Per Pythagoras: (5*5) + (12*12) = 13*13
Is it possible to construct a triangle with side lengths 12 cm 15 cm and 25 cm?
a scalene triangle is a triangle with three differant sides
What side length can make a triangle with side lengths 8 and 12?
In order to construct a triangle the sum of its 2 smallest sides must be greater than its longest side.
A triangle with side lengths of 5 12 and 13 is which type of triangle?
Answer: Right Triangle Note that 25+144=169 which is 13 squared. This tells us it is a right triangle.
what- Suppose the side lengths of a triangle have the ratio 5:12:13. Some possible triangles are shown here. Now suppose the perimeter of the triangle is ninety centimeters.What are the side lengths?
What is the triangle
What is the area of a triangle that is 12 in and 16 in?
What is 12 in ? And what is 16 in ? ? Are they the lengths of two sides of the triangle ? Are they the length of one side and the height of the triangle ? The area of any triangle is 1/2 of the product of (length of its base) x (its height).
Can the measures 1012 and 16 be side lengths of a triangle?
If you mean sides of 10, 12 and 16 then yes a triangle be constructed because the sum of its 2 smaller sides is greater than its longest side.
What is the length of the hypotenuse of a right triangle with legs of lengths 5 and 12?
The length of the hypotenuse of a right triangle with legs of lengths 5 and 12 units is: 13The length of a hypotenuse of a right triangle with legs with lengths of 5 and 12 is: 13
