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.

The perimeter of a triangle is found by adding all 3 sides of the triangle. This is most commonly expressed using the formula for a triangle's perimeter: a+b+c=P. Where P is perimeter and a,b,and c are the three sides.

A hypotenuse is the longest side of a right angled triangle. The length of a hypotenuse can be found using the Pythagorean Theorem. This states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This means that to find the length of the hypotenuse, you need to know the lengths of the other two sides.

A real life example of a right-angled triangle would be a ladder leaning against a wall. And a acute triangle is an example of a umbrella. Some types of an umbrella are divided into a few sections using triangles edit by: A.B

Using Pythagoras' theorem the longest side which is the hypotenuse works out as 10cm

By using the formula a2+b2=c2, where a is one side of the right-angled triangle and b is the other side of the right angle triangle. C stands for the hypotenuse of the right-angled triangle. Note: this formula only works for RIGHT-ANGLED TRIANGLES!!!

The answer depends on what other information you have about the triangle.

no. If it is a right angled triangle. Then using Pythagoras' formula a2 +b2 =c2

Yes they do for a triangle using Pythagorean theorem 5 squared + 12 squared = 13 squared

If its a right angled triangle, try using Pythagoras to check.... x

thePythagoras theorem was simply to calculate the sides of a right angled triangle, isosceles triangle and cubes and cuboids here is the formulas; right angled triangle= a^2+b^2=c^2 for an isosceles triangle, split it in half and you have two right angled triangles, use the formula above afterwords cube/cuboids, you can find the face diagonal and the space diagonal by using the formula above to calculate if it is a right angled triangle or not, then you need the 3 sides( a, b and c)add a^2 and b^2, then calculate c^2, if a^2+b^2 is equal to c^2, then it is a right angled triangle, if not, then it isn't a right angled triangle by the converse of Pythagoras, hope this helped :-) hope its not to complicated for you!

u have to imagine it revolving... only this way it's possible to form a double cone with a right triangle.

using Pythagoras; check if 122 = 92+82 the equation is false then no it isn't a right triangle

Using Pythagoras' Theorum: (height)^2 = (hypotenuse)^2 - (base)^2

Using the trigonometry ratio for the cosine and by halving the base lenght which will result in two right angled triangles. Then after working out the hypotenuse simply double it and add on the original base length.

Using Pythagoras' theorem and the quadratic equation formula the sides of the triangle work out as 6.25 cm and 15 cm. Therefore the perimeter of the right angle triangle is: 6.25+15+16.25 = 37.5 cm
