## Is it possible to make a triangle with given side lengths?

SOLUTION: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, , you can not form a triangle with side lengths 4 ft, 9 ft, 15 ft. The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

### Can these 3 sides make a triangle?

Can three equal side lengths form a triangle? Yes. It’s called an equilateral triangle, and it can work because two side lengths added together are bigger than the third side.

**What type of triangle can be formed with sides measuring 8 inches 8 and 3 inches?**

Answer: An isosceles triangle is the correct answer.

**Is it possible to have a triangle such that the sum of the measures of the small and medium sides is equal to the measure of the large side?**

Is it possible to have a triangle such that the sum of the measures of the small and medium sides is equal to the measure of the large side? Explain. No, it is not possible.

## What is the rule for side lengths of a triangle?

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side. See the side lengths of the acute triangle below. The sum of the lengths of the two shortest sides, 6 and 7, is 13.

### What is the shortest side of a 30 60 90 triangle?

Explanation: Ina 30-60-90 right triangle the shortest side which is opposite 30 degree angle is half of the hypotenuse.

**How do you find an angle of a triangle with 3 sides?**

“SSS” is when we know three sides of the triangle, and want to find the missing angles….To solve an SSS triangle:

- use The Law of Cosines first to calculate one of the angles.
- then use The Law of Cosines again to find another angle.
- and finally use angles of a triangle add to 180° to find the last angle.

**What does a scalene triangle look like?**

Scalene triangles have three unequal angles. The shortest side is opposite to the smallest angle, The medium side is opposite to the medium angle, The longest side is opposite the largest angle.

## What is the missing side length of this right triangle?

Answer. 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.

### What is the rule for 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. Pythagorean Theorem: In a right triangle with hypotenuse .

**Can the following side measures form a triangle 3/5 8?**

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

**Can a scalene triangle be a right triangle?**

A scalene triangle is a triangle in which all three sides have different lengths and all angles are diferent too. This type of triangle can be a right triangle (one angle with measure 90°) but not all scalene triangles have a right angle.

## What is the sum of all three angles of a scalene triangle?

A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees.

### How to calculate the perimeter of a scalene triangle?

Perimeter of a Scalene Triangle. The perimeter of a triangle is equal to the sum of the length of sides of a triangle and it is given as. Perimeter = a + b + c units.
