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
