Is it possible to have a triangle with sides 3 inches 4 inches and 8 inches? SOLUTION: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. 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**.

## Can a triangle have any 3 lengths of sides?

Can any three lengths make a triangle? **The answer is no**. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.

## Can triangles have any side lengths?

According to the first triangle inequality theorem, **the lengths of any two sides of a triangle must add up to more than the length of the third side**. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.

## How do you determine if a triangle is valid?

Approach: A triangle is valid **if sum of its two sides is greater than the third side**. If three sides are a, b and c, then three conditions should be met.

## Could 5'2 and 3 form a triangle?

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

What makes a triangle not possible?

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. In other words, as soon as you know that the sum of 2 sides is less than (or equal to) the measure of a third side, then you know that the sides do not make up a triangle.

Does a triangle with side lengths 15 12 9 exist?

Therefore yes, it is a right triangle.

What lengths make a triangle?

Do triangle sides equal 180?

No matter how you position the three sides of the triangle, the total degrees of all interior angles (the three angles inside the triangle) is always 180°.

How do you check a triangle is valid or not using angles?

Approach: A triangle is valid if the sum of the three angles is equal to 180 degrees.

Is it possible to have a triangle with the following sides 2cm 3cm 5cm?

In a triangle, the sum of the lengths of either two sides is always greater than the third side. Given that, the sides of the triangle are 2 cm, 3 cm, 5 cm. Hence, this triangle is not possible.

Is the triangle with sides 3cm 6cm and 9cm possible?

Yes it is possible.

How do you find the third side of a triangle?

Which three lengths can not be the lengths of the sides of a triangle *?

Sat Mathematics : Example Question #6

A triangle has sides of length 8, 13, and L. Which of the following cannot equal L? Explanation: The sum of the lengths of two sides of a triangle cannot be less than the length of the third side.

How do you determine a triangle by its side lengths?

What are the 2 shorter sides of a right triangle called?

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.

Does this make a right triangle?

What is the name for side C?

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

What triangle is 104?

Obtuse triangles

The 118 degrees angle label is highlighted. A triangle with angle measures of 104 degrees, 42 degrees, and 34 degrees.

What is the sum of 3 sides of a triangle?

When it has three line segments joined end to end. Thus, we can say that a triangle is a polygon, which has three sides, three angles, three vertices and the sum of all three angles of any triangle equals 180°.

In which case of the following lengths of sides of a triangle is it possible to draw a triangle?

No, it is not possible to construct a triangle with lengths of its sides as 4 cm, 3 cm and 7 cm because here we see that sum of the lengths of two sides is equal to third side i.e., 4+3 = 7. As we know that, the sum of any two sides of a triangle is greater than its third side, so given statement is not correct.
