If it is then 742 would equal 702 + 242.
742 = 5476; 702 = 4900, 242 = 576.
Pythagoras is satisfied so your triangle is indeed right-angled.
false In order for this to be a right triangle, the sum of the squares of the two shorter sides would have to equal the square of the longest side. 102=100 242= 576 272=729 102+242= 676, which does not equal 272=729, so a triangle with these lengths is not a right triangle.
We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the right triangle. The Pythagorean theorem gives the relationship between the lengths of the sides of a right triangles. In the case where you know only the measure lengths of the sides of a triangle, you need to test these measures. If one of the sides of the triangle has a square measure equal to the sum of the square measures of two other sides, then this side is called the hypotenuse and opposite to this side is a 90 degree angle, which is a right angle. So, you can say that this triangle is a right triangle. Pythagorean triple are very helpful to determine a right triangle, such as: (3, 4, 5), (5,12,13), (8, 15, 17), (7, 24, 25), and (20, 21, 29).
An isoceles triangle! It has two lengths the same!
You need THREE sides for a triangle. Once you have them, you can check with the Pythagorean theorem whether it is a right triangle: the square of the longest side must be equal to the sum of the squares of the other two sides.
Any three numbers, a, b, and c, which satisfy the equation a2 + b2 = c2 will form the sides of a right triangle. Some common values are 3, 4, 5 (and all multiples), 5, 12, 13 (and all multiples), and 7, 24, 25 (and all multiples).
Yes, it is.
No because it does not comply with Pythagoras; theorem if the lengths were 10, 24 and 26 then it would be.
Does 742 = 242 + 702? If so, it is a right-angled triangle; if not, it isn't...
Yes because they comply with Pythagoras' theorem for a right angle triangle
True because it complies with Pythagoras' theorem.
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.
8cm !
No. But they can be the lengths of the three sides.
false In order for this to be a right triangle, the sum of the squares of the two shorter sides would have to equal the square of the longest side. 102=100 242= 576 272=729 102+242= 676, which does not equal 272=729, so a triangle with these lengths is not a right triangle.
It would be an isosceles right triangle. The two sides that aren't the hypotenuse are equal, with lengths of 16.971 (rounded) .
24cm each
A triangle is right triangle if square of the longest side is equal to sum of squares of other two sides. Square of 24 = 576 Sum of square of 9 and 21 = 92 + 212 = 81 + 441 = 522 576 ≠522. It is clear that triangle is not a right triangle.
