Is 7 8 12 a right 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.


How do you find the permiter of a 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.


What is the length of a hypotenuse?

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.


You are looking for real life examples of isosceles equilateral right triangle obtuse triangle and acute triangle?

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


What is the length of the longest side of a right angled triangle if the two shorter sides are 6cm and 8cm?

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

How can you calculate the length of the hypotenuse of a right angle triangle?

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!!!

What is the thoerem of Pythagoras?

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!

What is the height of a right angled triangle?

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


When the vertex angle and the base of an isosceles triangle are given how do you find its perimeter?

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.


What is the perimeter of a right angle triangle that has an hypotenuse of 16.25 cm and an area of 46.875 square cm?

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
