**How Many Sides Does A Triangle Have? A triangle has three sides.**

**What is a rule to tell if three sides will make a triangle or not?** There is no definitive answer to this question, as it depends on the specific angles involved. However, in general, if all three angles are less than 90 degrees, then the three lines will likely form a triangle.

**Do triangles actually have 4 sides?** Some people say that triangles have 4 sides, while others say that they have 3 sides. The truth is that this depends on the type of triangle. Equilateral triangles do have 4 sides, while scalene and isosceles triangles have only 3 sides.

**How do you find the 3 length of a triangle?** There are a few ways to find the length of a triangle. One way is to use the Pythagorean theorem, which states that the sum of the squares of the two shorter sides is equal to the square of the length of the longer side. Another way is to use trigonometry to find the length of the triangle’s sides.

## Frequently Asked Questions
