What will be the length of the hypotenuse of a right-angled triangle if its perpendicular sides measure 20 cm and 21 cm?

Length of Hypotenuse is 13 cm.

How long is the hypotenuse of a right triangle whose legs are 4 cm and 8 cm?

hence the length of the hypotenuse is 17 units.

What is the length of the hypotenuse of the triangle 26?

Explanation: By Pythagoras Theorem, a2+b2=c2 . Since the hypotenuse, c is 26 feet long, 262 = 676.

How do you find the legs of a triangle?

Given two sides

1. if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)
2. if leg b is unknown, then. b = √(c² – a²)
3. for hypotenuse c missing, the formula is. c = √(a² + b²)

What is the hypotenuse of 8 and 15?

Find the length of the hypotenuse of a right triangle whose legs are 8 and 15units in length. Summary: The length of the hypotenuse of a right triangle whose legs are 8 and 15 units in length is 17units.

What is hypotenuse math?

Definition of hypotenuse 1 : the side of a right-angled triangle that is opposite the right angle.

How do you find the hypotenuse of a triangle with one leg?

Use the Pythagorean theorem to calculate the hypotenuse from right triangle sides. Take a square root of sum of squares: c = √(a² + b²) Given angle and one leg. c = a / sin(α) = b / sin(β), from the law of sines. Given area and one leg.

What are the legs of a right triangle called?

The two perpendicular sides are called the legs of a right triangle, and the longest side that lies opposite the 90-degree is called the hypotenuse of a right triangle. A right triangle can be scalene (having all three sides of different length) or isosceles (having exactly two sides of equal length). It can never be an equilateral triangle.

How do you find the legs of an isosceles triangle?

For isosceles triangles, the two equal sides are known as the legs, while in an equilateral triangle all sides are known simply as sides. How do I find the hypotenuse adjacent and opposite? Find the longest side and label it the hypotenuse. The adjacent and opposite can only be found if you choose one of the non right angled angles.

What is the Pythagorean theorem for an isosceles right triangle?

Now, in an isosceles right triangle, the other two sides are congruent. Therefore, they are of the same length “l”. Thus, the hypotenuse measures h, then the Pythagorean theorem for isosceles right triangle would be: (Hypotenuse) 2 = (Side) 2 + (Side) 2. h 2 = l 2 + l 2. h 2 = 2l 2.
