# How do you do C and Pythagorean Theorem?

## How do you do C and Pythagorean Theorem?

The hypotenuse formula is simply taking the Pythagorean theorem and solving for the hypotenuse, c . Solving for the hypotenuse, we simply take the square root of both sides of the equation a² + b² = c² and solve for c . When doing so, we get c = √(a² + b²) .

## Does 6 in 8 and 10 make a right triangle?

Answer: Yes, a triangle has side lengths 6, 8, 10 is it a right triangle.

## Is C the hypotenuse?

While C is the longest side which lies opposite to the right angle is Hypotenuse.

## What is B in Pythagorean Theorem?

Pythagorean Theorem for Right Triangles a = side leg a. b = side leg b. c = hypotenuse.

## How do engineers use Pythagorean Theorem?

Engineers and astronomers use the Pythagorean Theorem to calculate the paths of spacecraft, including rockets and satellites. Architects use the Pythagorean Theorem to calculate the heights of buildings and the lengths of walls.

## How do you classify a triangle by its side lengths?

Classifying Triangles by Sides

1. scalene triangle-a triangle with no congruent sides.
2. isosceles triangle-a triangle with at least 2 congruent sides (i.e. 2 or 3 congruent sides)
3. equilateral triangle-a triangle with exactly 3 congruent sides.
4. NOTE: Congruent sides means that the sides have the same length or measure.

## How do you use Pythagorean theorem when B is missing?

To find b: using Pythagorean theorem,

1. find the square value of side c.
2. find the square value of side a.
3. Subtract c^2 from a^2.
4. Find the root square value of the difference is the value of b.

## Can the hypotenuse be equal to a leg?

The correct answer is Triangle B. You can use the same formula to find the length of a right triangle’s leg if you are given measurements for the lengths of the hypotenuse and the other leg.

## Can the legs ever be longer than the hypotenuse?

A leg cannot be longer than the hypotenuse. The largest angle in a right triangle is 90 degrees. opposite the 90 degree angle is the largest side.

## Is the hypotenuse the longest side 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. The hypotenuse of a right triangle is always the side opposite the right angle.

## How do you know if a triangle is obtuse by side lengths?

Use the Three Side Lengths to Find Out On the other hand, if a squared plus b squared is less than c squared, the triangle will have an obtuse angle and be obtuse. For example, if you have a triangle with side lengths of 4, 10, and 15, you can plug these lengths into the equation.

## Is Side A always longer than Side B in a right triangle?

2 Answers. Side A and B does not matter when your trying to apply this to the pythagorean theorem but side C must always be the hypotenuse. The hypotenuse is always the triangle’s longest side. It is opposite the right angle.

## How is Pythagorean theorem used in real life?

The Pythagorean Theorem is useful for two-dimensional navigation. You can use it and two lengths to find the shortest distance. … The distances north and west will be the two legs of the triangle, and the shortest line connecting them will be the diagonal. The same principles can be used for air navigation.

## How do you use the Pythagorean theorem to solve a right triangle?

Right Triangles and the Pythagorean Theorem

1. The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
2. The side opposite the right angle is called the hypotenuse (side c in the figure).

## Is the converse of the Pythagorean theorem true?

The converse of the Pythagorean Theorem is also true. Pythagorean Theorem Converse: If the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.

## Does Trig work for non right triangles?

So far, we’ve only dealt with right triangles, but trigonometry can be easily applied to non-right triangles because any non-right triangle can be divided by an altitude * into two right triangles.

## How can you use Pythagorean theorem to solve problems?

Step 1: Draw a right triangle and then read through the problems again to determine the length of the legs and the hypotenuse. Step 2: Use the Pythagorean Theorem (a2 + b2 = c2) to write an equation to be solved. Step 3: Simplify the equation by distributing and combining like terms as needed.

## How do you find A2 and B2 with only C2?

Introduction: Pythagorean Theorem The formula is A2 + B2 = C2, this is as simple as one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.

## How do you use the Pythagorean theorem to determine a triangle?

Classifying Triangles by Using the Pythagorean Theorem If you plug in 5 for each number in the Pythagorean Theorem we get and 50>25. Therefore, if a2+b2>c2, then lengths a, b, and c make up an acute triangle. Conversely, if a2+b2triangle.

## Why is the hypotenuse of a right triangle longer than a leg of the triangle?

Since a right angle is half that (90°), it has to be the biggest angle in the triangle and the side across from it will always be the longest. …

## Can these 3 sides make a triangle?

As stated above, as long as the sum of any two of those measurements is greater than the third measurement, the three “sides” will fit together to make a triangle. In the case of the three numbers you propose, they will form a triangle.

hypotenuse

## What is the importance of Pythagorean Theorem?

The discovery of Pythagoras’ theorem led the Greeks to prove the existence of numbers that could not be expressed as rational numbers. For example, taking the two shorter sides of a right triangle to be 1 and 1, we are led to a hypotenuse of length , which is not a rational number.

## How do you know if a triangle is acute or obtuse by side lengths?

When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:

1. Square all 3 sides.
2. Sum the squares of the 2 shortest sides.
3. Compare this sum to the square of the 3rd side.
