TriSolve

Free💲 (see ⭐ below)

The only triangle solver that draws the values you enter and enters the values you draw.

Perfect for:

• Geometry teachers and students 🎓

• Construction and carpentry projects 🚧

• Navigation and orienteering ⛵

• Machinists and engineers ⚙️

• Physics, math, and astronomy 🪐

• Surveying 🌲

• Anyone solving triangles 📐

Both solve for AND ENTER: ✅

• Sides

• Angles

• Vertices

• All 3 Heights

• Perimeter

• Area

• Multiple Centers

Key Features: 🔑

• Identify and solve ambiguous triangles.

• Partial solutions. (e.g. Base and height alone solves for area)

• Inverse calculations. (e.g. Enter area and height to solve for base)

• Translate, rotate, reflect and scale transformations.

• Categorize scalene, isosceles, equilateral triangles.

• Categorize acute, right, and obtuse triangles.

Drawing Features: ✏️

• User drawable sides, angles and vertices.

• Automatic center, zoom and orientation.

• Precision aware drawing.

• Axis lock on xy and rθ vertices.

• Zoom and pan graphics.

Numeric Features: 1️⃣2️⃣3️⃣

• 15 angle units. (deg°, rad, d°m's", % grade, 𝜏, +...)

• Metric, SAE, and universal length units.
