Challenge 3: Why Hand-Drawing a Rectangle With the Pen Tool Is the Harder Path — Solution Walkthrough

The answer:

Drawing a rectangle by hand with the Pen tool means manually placing
four corner points and making sure each connects at a precise right
angle, and closing the path correctly back to the starting point —
several manual steps, each with room for a small inaccuracy, just to
produce an extremely regular, predictable shape.

Why this chapter frames it as the harder path:

Per this chapter's own tip box, regular geometric shapes don't need to
be drawn point by point at all — Chapter 4 introduces dedicated shape
tools that build a mathematically precise rectangle, circle, or
polygon directly, with no manual point placement needed at all. The
Pen tool exists specifically for genuinely custom, irregular shapes
that don't already have a dedicated tool built for them.

Why this matters for a beginner's workflow:

Reaching for the Pen tool for every shape, including simple regular
ones, adds unnecessary manual work and unnecessary room for small
inaccuracies. Learning which tool is actually the right fit for a
given shape — Pen tool for custom paths, dedicated shape tools for
regular geometry — is part of working efficiently in either
application.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that hand-drawing a regular shape with the Pen
tool is correctly identified as unnecessary manual effort, with
Chapter 4's dedicated shape tools recognized as the more appropriate,
easier alternative for that specific case.
