Review Summary

Your solution is approved. All core functional requirements are met: the Figure interface is properly defined, all three shape classes implement it correctly, area calculations use the correct formulas (Heron's formula for triangles, Math.PI for circles, and proper validation for all shapes), and the getInfo method returns the required format. The getArea method correctly rounds to hundredths using Math.floor(area * 100) / 100, and constructor parameters use public modifiers as specified. There is one minor improvement you could consider: the triangle inequality error message currently hardcodes the text "Sides a, b and c can't form a triangle" instead of including the actual values passed. While the validation logic works perfectly, updating the error message to include ${a}, ${b}, and ${c} would provide more helpful feedback. This is a low-priority enhancement rather than a required fix since the validation itself functions correctly. Overall, this is solid, well-structured TypeScript code that demonstrates good understanding of interfaces, classes, and validation logic.
