Geometry build-up — arrange concepts from primitive to polygonal shapes: a) Point b) Triangle c) Square d) Angle e) Line

Introduction / Context:Order basic geometric entities up to common polygons.

Given Data / Assumptions:Point → Line → Angle → Triangle → Square.

Concept / Approach:Start with primitives and add structure.

Step-by-Step Solution:Point (a) is primitive.Line (e) extends points.Angle (d) forms from two rays.Triangle (b) is 3-sided polygon.Square (c) is 4-sided regular polygon.

Verification / Alternative check:Intro geometry builds polygons from lines and angles.

Why Other Options Are Wrong:They place polygons before angles/lines.

Common Pitfalls:Thinking square can precede triangles; both require angles/lines first.

Final Answer:a, e, d, b, c
