## Does a triangle have a right angle?

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle).

…

The side opposite the right angle is called the hypotenuse (side c in the figure)..

## How do you work out the longest side of a right angled triangle?

To calculate the length of a side on a right-angled triangle when you know the sizes of the other two, you need to use Pythagoras’ Theorem. Pythagoras’ Theorem says that, in a right angled triangle: The square of the hypotenuse is equal to the sum of the squares on the other two sides.

## What are the 2 shortest sides of a right triangle called?

Recall that a right triangle is a triangle where one of its angles is 90 degrees. For a right triangle, the side that is opposite of the right angle is called the hypotenuse. This side will always be the longest side of the right triangle. The other two (shorter) sides are called legs.

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

What is a 30-60-90 Triangle? A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle). Because the angles are always in that ratio, the sides are also always in the same ratio to each other.

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

A Quick Guide to the 30-60-90 Degree TriangleType 1: You know the short leg (the side across from the 30-degree angle). Double its length to find the hypotenuse. … Type 2: You know the hypotenuse. Divide the hypotenuse by 2 to find the short side. … Type 3: You know the long leg (the side across from the 60-degree angle).

## How do you tell if it 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.

## Does 20 25 15 represent a right triangle?

The largest length is always the hypotenuse. If we were to multiply any triple by a constant, this new triple would still represent sides of a right triangle. Therefore, 6, 8, 10 and 15, 20, 25, among countless others, would represent sides of a right triangle.

## What are the sides of a right triangle?

A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle. There are a couple of special types of right triangles, like the 45°-45° right triangles and the 30°-60° right triangle.

## How do you find the bottom side of a right triangle?

How to find the sides of a right triangleif 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)if leg b is unknown, then. b = √(c² – a²)for hypotenuse c missing, the formula is. c = √(a² + b²)

## How do you find the shortest side of a right angled triangle?

To find the length of a shorter sideSketch triangle.Mark hypotenuse.Write out pythagoras’ theorem for the triangle. (Hypotenuse)2 = (Shortest side)2 + (Other side)2Solve.Write out solution.

## What 3 side lengths form a right triangle?

We are given three sides of a triangle 3,4and6 . Pythagoras Theorem states that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

## Is Side C on a right triangle always the longest?

In this right triangle, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest side of the triangle.

## 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°).

## Does 9 12 and 15 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.

## How do you find the length of the longest side of a triangle?

The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle. Triangle Inequality: In any triangle, the sum of the lengths of any two sides is greater than the length of the third side.

## Which is the shortest side of a right triangle?

The shortest side is the one opposite the smallest angle.

## What side is C on a triangle?

hypotenuseThe sides of a right triangle have different names: The longest side, opposite the right angle, is called the hypotenuse. In the diagram, the hypotenuse is labeled c. The other two sides are called the legs of the triangle.

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

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. Any triangle of the form 30-60-90 can be solved without applying long-step methods such as the Pythagorean Theorem and trigonometric functions.

## Does 5 12 and 13 form a right triangle?

Answer and Explanation: Yes, a right triangle can have side lengths 5, 12, and 13.

## What is C in a triangle?

c. In any right-angled triangle, ABC, the side opposite the right-angle is called the hypotenuse. Here we use the convention that the side opposite angle A is labelled a. The side opposite B is labelled b and the side opposite C is labelled c.

## Are the sides of a right triangle equal?

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. … The Egyptians used this triangle for land surveying.
