# How do you find the area for a triangle?

## How do you find the area for a triangle?

You can find the area of a triangle by multiplying the base by the height and then dividing that number by 2. For example, if you have a triangle with a base of 4cm and a height of 2cm, then you would have an area of 4cm squared because 4 times 2 equals 8, and 8 divided by 2 equals 4.

**How do you find the area of a triangle given 2 sides and an angle?**

If you know 2 of these 3 sides an you know the angle between them you can find the area of the triangle very simple: Area= (a x b x sin c)/2, where a, b are the two sides and c is the angle between them. That’s it!

### How do you find the base and the height of a triangle?

Triangle area formula area = 0.5 * b * h , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.

**How do you find the height and area of a triangle?**

How to find the height of a triangle – formulas

- area = b * h / 2 , where b is a base, h – height.
- so h = 2 * area / b.

## What is the height of a right triangle?

The height of a triangle is the distance from the base to the highest point, and in a right triangle that will be found by the side adjoining the base at a right angle.

**Does 4 5 6 make right triangles?**

The three numbers 4, 5, 6 make a Pythagorean Triple (they could be the sides of a right triangle).

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

A right triangle is a triangle in which one of the angles is a 90∘ angle. 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.

**How do you use the Pythagorean theorem to find a right triangle?**

Right Triangles and the Pythagorean Theorem

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

## Does 10 15 20 Make 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.

**Does 4 8 12 make right triangles?**

Answer: No, side lengths of 4, 8, and 12 do not form a right triangle.

### Are 8 15 and 17 a Pythagorean triple?

is a Pythagorean triple are shown above for successively larger bounds. always odd. In addition, one side of every Pythagorean triple is divisible by 3, another by 4, and another by 5. One side may have two of these divisors, as in (8, 15, 17), (7, 24, 25), and (20, 21, 29), or even all three, as in (11, 60, 61).

**Why do we justify 5 7 9 Pythagorean triplets?**

Answer: No 5 7 9 isn’t a Pythagorean template. because square of 5 and 7= and square of 9 is 81. that’s why 5 7 9 is not a Pythagorean triplate.

## What type of triangle is 8 15 17?

If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc.

**What are the 5 most common Pythagorean triples?**

Examples

(3, 4, 5) | (5, 12, 13) | (7, 24, 25) |
---|---|---|

(20, 21, 29) | (12, 35, 37) | (28, 45, 53) |

(11, 60, 61) | (16, 63, 65) | (48, 55, 73) |

(13, 84, 85) | (36, 77, 85) | (65, 72, 97) |

### What is the Pythagorean Triplet of 14?

Pythagorean triplet, whose one member is 14, is 14, 48, 50.

**What is a 45 degree triangle?**

A 45°-45°-90° triangle is a special right triangle that has two 45-degree angles and one 90-degree angle. The side lengths of this triangle are in the ratio of; Side 1: Side 2: Hypotenuse = n: n: n√2 = 1:1: √2. The 45°-45°-90° right triangle is half of a square.

## Are there infinite Pythagorean triples?

There are an infinite number of Pythagorean triples. But 2 n +1 comprises all the odd numbers; every other square numbers is odd; there are an infinite number of odd squares; hence there are an infinite number of Pythagorean triples.

**Is there a pattern to Pythagorean triples?**

If you square each number, subtract one square from the square greater than it, then square root this number, you can find Pythagorean Triples. 289 – 225 = 64 = 8^2 so (8, 15, 17) makes up a Pythagorean Triple. The first square number is always even and increases by two each time.

### How do you know if a number is a Pythagorean triple?

The square of the length of the hypotenuse of a right triangle is the sum of the squares of the lengths of the two sides. This is usually expressed as a2 + b2 = c2. Integer triples which satisfy this equation are Pythagorean triples. The most well known examples are (3,4,5) and (5,12,13).

**What is the Pythagorean Triplet of 8?**

∴ The triplet is (6, 8, 10) but 8 is not the smallest number of this triplet. ∴ The triplet is (8,15,17) and 8 as the smallest member of the triplet.

## What will be a Pythagorean triplet whose smallest member is 8?

The triplet is therefore 6, 8, 10. hence, 8 is not the smallest method of this. The triplet is 8, 18, 17 with 8 as the smallest number.

**How do you find the Pythagorean Triplet of 7?**
