## How do you solve special right triangles?

Step 1: This is a right triangle with two equal sides so it must be a 45°-45°-90° triangle.

Step 2: You are given that the both the sides are 3.

If the first and second value of the ratio x:x:x√2 is 3 then the length of the third side is 3√2.

Answer: The length of the hypotenuse is 3√2 inches..

## What is the formula for a right angle triangle?

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.

## What are the properties of 30 60 90 Triangle?

What is a 30-60-90 Triangle?The side opposite the 30º angle is the shortest and the length of it is usually labeled as x.The side opposite the 60º angle has a length equal to x\sqrt3.The side opposite the 90º angle has the longest length and is equal to 2x.Jan 13, 2019

## What is the area of the triangle?

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.

## What are the equivalent side ratios for a 30 60 90 Triangle?

This means that the ratio of the lengths of the shortest side to the hypotenuse of any 30-60-90 right triangle is 1:2. Therefore, If a triangle is a 30-60-90 right triangle, the ratio of the sides (short leg:long leg:hypotenuse) is 1:√3:2.

## Which of the following are true statements about a 30 60 90 Triangle?

Answer Expert Verified A 30-60-90 triangle is a right triangle with one leg equal to x, the other leg equal to 2x and the hypotenuse equal to x*sqrt(3). So, there you see that the longer leg is twice as long as the shorter leg (option D) and the hypotenuse is sqrt(3) times as long as the shorter leg (option F).

## How do you solve a 30 60 90 Triangle calculator?

In a 30 60 90 special right triangle the hypotenuse is always equal to twice the length of the shortest leg. Thus, the formula to calculate the hypotenuse c is simply c = 2a.

## Which side is the short leg of this 30 60 90 Triangle?

HypotenuseRelationship Between the. Short Leg and Hypotenuse The short leg of a 30-60-90 triangle is always 1/2 the length of the hypotenuse.

## What is the ratio of sides?

Ratios and Proportions – Similar figures – In Depth. If two objects have the same shape, they are called “similar.” When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides.

## How do you know if a triangle is a right triangle?

A right triangle is a triangle in which one of the angles is a 90∘ angle. The “square” at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.

## What is the formula for 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.

## 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.

## What are the rules for 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.

## How do I find the length of a triangle?

Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is a2+b2=c2 a 2 + b 2 = c 2 , which is known as the Pythagorean Theorem.

## How do you find the area of a 90 degree triangle?

Area of right triangle formulasIf you know one angle and hypotenuse, you can use the law of sines: a = c * sin(α) b = c * sin(β) = c * sin(90-α) = c * cos(α) area = c² * sin(α) * cos(α) / 2.Given one angle and one leg, find the area using e.g. trigonometric functions: a/b = tan(α) and b/a = tan(β)Jun 26, 2020
