The task requires area rounded down to hundredths, but toFixed(2) rounds to nearest. For rounding down, use Math.floor(area * 100) / 100 pattern (similar to the Circle implementation on line 49).

Review Summary
Your implementation has solid logic for area calculations, proper error handling, and correct validation. However, the code does not meet the explicit requirements for enum usage.
Critical issues that must be fixed:
-
Missing
Shapeenum — The requirements explicitly state: "Use enum forshapewith values:Triangle,Circle,Rectangle". Currently, your code uses string literals like'triangle','circle','rectangle'. You need to define aShapeenum and use it in yourFigureinterface and all implementing classes. -
Missing
Colorenum — The requirements explicitly state: "Use enum forcolorwith values:Red,Green,Blue". Currently, your code uses the plainstringtype. You need to define aColorenum and use it for thecolorproperty throughout your implementation.
How to fix:
Define the enums at the top of your file:
enum Shape { Triangle, Circle, Rectangle }
enum Color { Red, Green, Blue }Then update your Figure interface and class properties to use these enums instead of string types.
All your functional logic is correct — just add the enum definitions to meet the requirements.

The code uses string literals for shape properties instead of enums. Requirements specify: 'Use enum for shape with values: Triangle, Circle, Rectangle'. The shape should be typed using a Shape enum.

Review Summary
Your solution is approved. Excellent implementation of the Figure interface with all three shape classes properly implementing the required getArea method. The enums use correct naming conventions (capitalized constants with lowercase string values), validation logic handles edge cases appropriately (positive dimensions and triangle inequality), and the area calculations are accurate using Heron's formula and Math.PI. The getInfo function produces the expected output format, and the use of constructor parameter modifiers (public color) follows TypeScript best practices [CHECKLIST ITEM #4]. Well done!
