A triangle with sides of lengths 12 15 and 20 is a right triangle?

False. It can't be.
In a right triangle, the sum of the squares of the two short sides is equal to the square
of the longest side.
122 = 144
152 = 225
-------------
sum = 369
202 = 400, not 369.
So these are not the sides of a right triangle.

Do 5 12 13 form a right angled triangle?
Yes they do for a triangle using Pythagorean theorem 5 squared + 12 squared = 13 squared
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
Can a triangle with side lengths 9 feet 12 feet and 15 feet be a right triangle?
Yes.
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.
Find the lengths of the side of the right triangle if the longest side of the triangle is four more than the shortest side and the middle side is two more than the shortest side?
There is no such right triangle. You have defined the relationship between three sides of a triangle that does not have a 90 degree angle. In a right triangle the sum of the squares of the shorter sides equals the square of the longest side and 12 + 22 = 5 ; 42 = 16 it does not equal 5 The angles in a triangle with sides 1, 2, 4 units can be found by applying the cosine rule.
Can 12 13 and 18 be lengths of the sides of a right angle triangle?
No because they don't comply with Pythagoras' theorem.
Do 5 12 13 form a right angled triangle?
Yes they do for a triangle using Pythagorean theorem 5 squared + 12 squared = 13 squared
What represents the lengths of the sides of an isosceles triangle?
12, 7, 7
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
What triangle has a length or 12 12 24?
A triangle can't have sides with lengths of 12, 12, and 24. Well, maybe you might call it a 'degenerate' triangle', with angles of 0°, 0°, and 180°. The two sides of 12 and 12 together are just exactly long enough to reach from one end of the 24 to the other, so they flop down and lie right on top of it. When you look at this 'triangle', it looks like a single line with a length of 24.
Can a right triangle have side lengths of 12 14 and 18?
no.
Is A triangle with sides of lengths 12 15 and 20 a right triangle?
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.
Do the lengths 7 10 12 make a right angle?
No, they do not represent a right triangle.

a scalene triangle is a triangle with three differant sides
Can a triangle with side lengths 9 feet 12 feet and 15 feet be a right triangle?
Yes.
Can the numbers 7 9 and 12 be the lengths of the sides of a right triangle?
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
Can a right triangle have sides of 10 and 12?
Yes.
