Part 1: Creating Your Triangle

Create your own triangle with the following conditions:

The triangle cannot be isosceles or equilateral.

The longest side cannot be greater than 7 units.

The shortest side cannot be less than 1 unit.

Sides must be rational values.

Prove your three sides can form a triangle, then connect the segments to build it.

Start here

Choose Your Three Side Lengths

Pick three lengths that meet the conditions and type them shortest to longest — they become a, b, c, so a is your shortest side.

Prove Your Triangle Exists

Substitute your three side lengths into all three Triangle Inequality checks, then simplify each one — each pair of sides must add to a sum that is greater than the third side.

🔒 Finish step 1 above to unlock these checks.

Build Your Triangle

Drag a segment by its middle to slide it; drag an end to swing it around the other end. Ends snap together — close all three corners, and the vertices name themselves.

🔒 Pass all three checks above to unlock the segments.

Slide a segment until its end touches another end. 0 / 3
