Yes they do for a triangle using Pythagorean theorem 5 squared + 12 squared = 13 squared
Sides of lengths 5, 12 and 13 do not form a right angle, but a right angled triangle.
Yes.
A triangle with the above dimensions would be a right angled triangle.
yes.
The two other sides are 5 cm and 12 cm because they comply with Pythagoras' theorem for a right angle triangle.
57.6 is the length of the perimeter. A right angled triamgle follows the '3-4-5' length constant. If 24 represents the 5, then 25/5=4.8. Then the sum of the sides (3+4+5=12). 12 * 4.8 = 57.6. Simple
10^2 + 12^2 is not equal to 16^2, so it is not a right triangle.
A triangle with the above dimensions would be a right angled triangle.
7, 8 & 12 are the sides of the triangle.And, for a right angled triangle the Pythagoras theorem is always applicable!Pythagoras theorem states that for a right angled triangle:(Longest Side)2 = (Side-1)2 + (Side-2)2(Longest side is called as the hypotenuse).So, using data in the question:If its a right angled triangle--->122 = 72 + 82i.e. 144 = 49 + 64 => 144 = 113, which is clearly not true!Hence, the triangle with the given sides is not a right triangle.
A right-angled triangle. Per Pythagoras: (5*5) + (12*12) = 13*13
No. Pythagoras' theorem states that when the square of the hypotenuse is equal to the sum of the squares of the other two sides then it is a right-angled triangle. The hypotenuse is the longest side (opposite the supposed right angle). In this case the hypotenuse is 20. The square of 20 is 400. The other two sides are 12 and 15. The square of 12 is 144 and the square of 15 is 225. The sum is therefore 225 + 144 = 369, which is not equal to 400, therefore the triangle cannot be a right-angled triangle.
yes.the property of right angled triangle is that the square of the hypotenuse is equal to the sum of other two sides thus (5*5)+(12*12)=169=(13*13)
1/2*12*35 = 210 km2
13 cm
yes.
if it makes a right angled triangle then c squared = a squared + b squared 12^2 = 7^2 + 9^2 144 = 49 + 81 but 144 doesn't equal 130 so no it doesn't make a right angle triangle
If you mean 5 by 12 by 13 then they will form a right angle triangle
9,3,6 The dimensions given above would not be suitable for a right angled triangle which presumably the question is asking about. The dimensions suitable for a right angled triangle in the question are: 9, 12, 15.
5" by 10" by 15" cannot be a right angled triangle because the square of the hypotenuse (longest side) must be equal to the sum of the squares of the other two sides.Proof:152 = 22552 + 102 = 25 + 100 = 125225 is not equal to 125 so the triangle is not a right angled triangle.All the others are right-angled triangles:92 + 122 = 152 [81 + 144 = 225]42 + 7.52 = 8.52 [16 + 56.25 = 72.25]1.52 + 22 = 2.52 [2.25 + 4 = 6.25]Answer9ft, 12ft, 15ft9² + 12² = 81 + 144= 225= 15²Which agrees with Pythagoras' Theorem, so this is a right-angled triangle.4cm, 7.5cm, 8.5cm4² + 7.5² = 16 + 56.25= 72.25= 8.5²Which agrees with Pythagoras' Theorem, so this is a right-angled triangle.5in, 10in, 15inThis one doesn't obey the triangle inequality, so it isn't a triangle at all. Anything that isn't a triangle isn't a right-angled triangle, and therefore we don't need to check it against Pythagoras' Theorem. But just to be thorough:5² + 10² = 25 + 100= 12515² = 225≠ 125Which disagrees with Pythagoras' Theorem, so this is not a right-angled triangle.1.5m, 2m, 2.5m1.5² + 2² = 2.25 + 4= 6.25= 2.5²Which agrees with Pythagoras' Theorem, so this is a right-angled triangle.
