## What are the lengths of a 30 60 90 Triangle?

What is a 30-60-90 Triangle.

A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º.

The triangle is special because its side lengths are always in the ratio of 1: √3:2..

## How do you find the longer leg of a 30 60 90 Triangle?

In any 30-60-90 triangle, you see the following: The shortest leg is across from the 30-degree angle, the length of the hypotenuse is always double the length of the shortest leg, you can find the long leg by multiplying the short leg by the square root of 3.

## How do you find the sides of a 30 60 90 Triangle?

30-60-90 Triangle RatioShort side (opposite the 30 degree angle) = x.Hypotenuse (opposite the 90 degree angle) = 2x.Long side (opposite the 60 degree angle) = x√3.Apr 14, 2020

## How do you find the hypotenuse of a 45 45 90 Triangle calculator?

The hypotenuse c is equal to the square root of leg a squared plus leg b squared. Note that in a 45 45 90 triangle legs a and b are the same length. The hypotenuse c is equal to leg a times the square root of 2.

## What is the length of a 45 45 90 degree angle?

Using the pythagorean theorem – As a right angle triangle, the length of the sides of a 45 45 90 triangle can easily be solved using the pythagorean theorem. Recall the pythagorean theorem formula: a 2 + b 2 = c 2 a^2+b^2=c^2 a2+b2=c2.

## What are the measurements of a 45 45 90 Triangle?

45°-45°-90° Triangles In a 45°−45°−90° triangle, the length of the hypotenuse is √2 times the length of a leg. To see why this is so, note that by the Converse of the Pythagorean Theorem , these values make the triangle a right triangle. Note that an isosceles right triangle must be a 45°−45°−90° triangle.

## What is the rule for a 45 45 90 Triangle?

That tells us that for every 45-45-90 triangle, the length of the hypotenuse equals the length of the leg multiplied by square root of 2. That is the 45-45-90 Triangle Theorem.

## How do you find the area of a 45-45-90 Triangle?

Correct answer: To find the area of a triangle, multiply the base by the height, then divide by 2. Since the short legs of an isosceles triangle are the same length, we need to know only one to know the other. Since, a short side serves as the base of the triangle, the other short side tells us the height.

## What is the length of each leg of a 45 45 90 Triangle?

11.31 cm3 Answers By Expert Tutors. Taking the square root of both sides gives x = 16 / (21/2) cm, which means that the length of each leg is approximately equal to 11.31 cm. The relationship of a 45-45-90 triangle sides is 1-1-√2.

## What is the 30-60-90 Triangle rule?

Tips for Remembering the 30-60-90 Rules Remembering the 30-60-90 triangle rules is a matter of remembering the ratio of 1: √3 : 2, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°).

## Is an isosceles right triangle always a 45-45-90 Triangle?

As these two angles are equal (the triangle being isoceles), each of the angle is 90o2=45o . Hence, an isosceles right triangle always a 45o−45o−90o triangle.

## What is the extended ratio relating the side lengths of a 45-45-90 Triangle?

Right triangles with 45-45-90 angles will have their ratio of the sides as 1:1:2.
