Shapes & Symmetry

Description

Four common polygons (triangle, square, pentagon, hexagon) are introduced one at a time.
For each shape a dashed symmetry line is drawn and the shape is reflected across it.
The square also demonstrates rotational symmetry with a spin animation.

Phases

#	Phase Name	Duration	Description
1	Title card	3 s	Title "Shapes & Symmetry" fades in
2	Triangle + reflection	7 s	Triangle appears; dashed line; right half fades/reflects
3	Square + reflection	7 s	Square; dashed line; half reflects; rotational spin
4	Pentagon + reflection	6 s	Pentagon; dashed vertical line; half reflects
5	Hexagon + reflection	6 s	Hexagon; dashed vertical line; half reflects
6	Summary gallery	5 s	All four shapes shown small side by side; fade out

Assets & Dependencies

• Fonts: Manim default (Text), LaTeX (MathTex)
• Colors: YELLOW (title), CYAN/GREEN/ORANGE/PINK (shape fills), WHITE (dashed lines)
• Background: #1a1a2e
• Manim version: ManimCE 0.19.1

Notes

• Shapes built with RegularPolygon (n=3,4,5,6).
• Reflection is achieved by creating a copy, flipping it with .flip(RIGHT), animating with Transform.
• Dashed line uses DashedLine.
• Rotational symmetry: square.animate.rotate(PI/2) repeated 4 times.
