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?
Given that the perimeter of the triangle is 90 centimeters, we can determine the actual side lengths by multiplying the ratio by a common factor. The total ratio value is 5 + 12 + 13 = 30. To find the actual side lengths, we divide the perimeter by this total ratio value: 90 / 30 = 3. Therefore, the side lengths of the triangle are 5 x 3 = 15 cm, 12 x 3 = 36 cm, and 13 x 3 = 39 cm.
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.
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.
