How do you know if three sides form a triangle in Java?

How do you know if three sides make a triangle in Java?


  1. If sum of length of any two sides is strictly greater than the length of third side then triangle can be constructed, else we cannot construct a triangle.
  2. Say sides lengths given are- a, b, c then to form a triangle, a+b>c and b+c>a, a+c>b. If any of the condition is not true, triangle cannot be formed.

How do you check if a triangle is possible in Java?

A Triangle is Valid only if one of the three sides of the triangle is greater than the other two sides. The Triangle Validity Test will find if the Triangle is valid or not which includes checking the following condition checking: First Side + Third Side > Second Side. Third Side + Second Side > First Side.

What is the rule for 3 sides of a triangle?

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

How do you check if it is a triangle?

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

Do three points always form triangles?

if not zero they can form triangle. A triangle can be drawn with three points iff these three points are three different points.

Does 9 12 15 form a right triangle?

Which set of sides could make a right triangle? Explanation: By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.

Is a degenerate triangle a triangle?

A degenerate triangle is the “triangle” formed by three collinear points. It doesn’t look like a triangle, it looks like a line segment. A parabola may be thought of as a degenerate ellipse with one vertex at an infinitely distant point.
