## What is the rule for triangle side lengths?

Triangle Inequality Theorem. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

**What is the rule for 3 sides of a triangle?**

To determine if 3 side lengths are a triangle, use the triangle inequality theorem, which states that the sum of 2 sides of a triangle must be greater than the third side. Therefore, all you have to do is add together each combination of 2 sides to see if it’s greater than the third side.

### Do the sides 3/4 and 6 make a triangle?

Hope this helped! Sridhar V. A triangle with sides of 3,4and6 is NOT a Right triangle.

**Can a triangle be 5 6 9 lengths?**

ANSWER: No; 11. SOLUTION: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

#### Are 3 4 5 triangles always right?

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. If you multiply the sides by any number, the result will still be a right triangle whose sides are in the ratio 3:4:5.

**How do you construct a triangle with sides 4cm 5cm and 6cm?**

- Draw base AB of side 4cm.
- With A as centre , and 5cm as radius, draw an arc.
- With B as centre , and 6cm as radius ,draw an arc.
- Let C be the point where two points intersect.
- Join AC and BC.

## Can 3cm 4cm and 5cm make a triangle?

YES, IT’S POSSIBLE! If the largest among the three sides of a triangle is lesser than the sum of the others, then it’ll be possible to draw the triangle. Here, in 3 cm, 4 cm, 5 cm, 5 cm is the largest.

**Is it possible to have a triangle with sides 6CM 3cm 2cm?**

According to the property of the triangle, the sum of the lengths of any two sides of the triangle should always be greater than the length of the third side. Therefore, the third required inequality is not getting satisfied, so it is not possible to have a triangle with sides having a measure of 6 cm, 3 cm, 2 cm.
