Abc is a right angled triangle ac equals 6cm bc equals 9cm work out the length of ab give your answer to 3 sig figures?
If angle ACB is the right angle then ab is the hypotenuse. Then,
(ab)2 = 62 + 92 = 36 + 81 = 117
ab = √117 = 10.8 (3 sf)
If angle BAC is the right angle then ab is one leg of a right angled triangle with bc the hypotenuse.
92 = 62 + (ab)2 : (ab)2 = 92 - 62 = 81 - 36 = 45
ab = √45 = 6.71 (3 sf)

Does a right-angled triangle have any equal sides?
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.
What is the length of the hypotenuse of the right triangle if AC equals 6 and AD equals 5?
The length of the hypotenuse of a right triangle if AC equals 6 and AD equals 5 is: 7.81
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.

Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
What statement is true about 45-45-90 triangle?
It is a right angled triangle with legs of equal length.
How do you calculate the length of a right angled triangle using the sine formulae?
The answer depends on what other information you have about the triangle.

Assuming a right angled triangle then the length would be 3. This is a pythagorean triangle with sides 3, 4, 5.
Is 5 a right triangle?
If the length of only one side is known, it is not possible to determine whether or not the triangle is right angled.
Is 10 a right triangle?
If the length of only one side is known, it is not possible to determine whether or not the triangle is right angled.
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!!!
