## What 3 lengths 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 12 8 and 4 make a right triangle?

The sum of 4 and 8 is 12 and 12 is less than 15 . This set of side lengths does not satisfy Triangle Inequality Theorem. These lengths do not form a triangle.

**Is a triangle with side lengths of 6 meters 8 meters and 10 meters a right triangle?**

They are equal, and thus, the triangle is a right triangle. Nghi N. When the side lengths of a triangle are in the ratio 3: 4: 5, then it is a right triangle. These sides are 6: 8: 10, then the triangle is a right one.

### Does 1 2 3 make right triangles?

Thus, 1,2,3 is not a Pythagorean triple and sides of such lengths cannot form a right triangle.

### Is 234 a right triangle?

Any triangle whose sides are in the ratio 3:4:5 is a right triangle. Such triangles that have their sides in the ratio of whole numbers are called Pythagorean Triples.

**Do the side lengths 4 8 10 form a triangle?**

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, , 3 in., 4 in., 8 in. do not form a triangle.

#### What makes 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.

#### Is a 3 4 5 triangle always a right triangle?

**Does 3 4 5 make right triangles?**

A 3-4-5 right triangle is a triangle whose side lengths are in the ratio of 3:4:5. In other words, a 3-4-5 triangle has the ratio of the sides in whole numbers called Pythagorean Triples.

## Do the lengths 2 3 and 4 make a triangle?

Can any three lengths make a triangle? The answer is no.

## Can you form a triangle with sides 2 4 and 8 units?

ANSWER: Yes; Find the range for the measure of the third side of a triangle given the measures of two sides.

**Can you make a triangle with these lengths?**

No; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

### How to calculate the areas of right triangles?

Let’s now see a bit more in-depth how to calculate areas of right triangles. The method for finding the area of a right triangle is quite simple. All that you need are the lengths of the base and the height. In a right triangle, the base and the height are the two sides which form the right angle.

### How do you find the hypothenuse of a right triangle?

A right triangle has two sides perpendicular to each other. Sides “a” and “b” are the perpendicular sides and side “c” is the hypothenuse. Enter the length of any two sides and leave the side to be calculated blank. Please check out also the Regular Triangle Calculator and the Irregular Triangle Calculator.

**What are the characteristics of a right triangle?**

Both its catheti are of the same length (isosceles) and it also has the peculiarity that the non-right angles are exactly half the size of the right angle that gives the name to the right triangle. This right triangle is the kind of triangle that you can obtain when you divide a square by its diagonal.

#### Which angles are smaller than the right angle of a triangle?

The other two angles will clearly be smaller than the right angle because the sum of all angles in a triangle is always 180°. In a right angled triangle the sides are defined in a special way. The side opposing the right angle is always the biggest in the triangle and receives the name of “hypotenuse”.
