How do you find the sides of a right triangle?

The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.

What are the 3 sides of a right triangle?

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.

How do you find one missing side of a right triangle?

How to find the sides of a right triangle

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)

Are 9 12 15 sides of a right triangle?

The three sides 9 in, 12 in, and 15 in do represent a right triangle. Since the square of the hypotenuse is equal to the sum of the squares of the other two sides, this is a right triangle.

Are 2 sides equal in a right triangle?

A right triangle has one angle equal to 90 degrees. A right triangle can also be an isosceles triangle–which means that it has two sides that are equal. A right isosceles triangle has a 90-degree angle and two 45-degree angles. This is the only right triangle that is an isosceles triangle.

Does 9 12 and 17 make a right triangle?

Explanation: By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.

Are all sides of triangle equal?

In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°….
