Question

geometry colored drawing (geometric)
rule: 1cm grid paper, colored drawing, fill fully as required, label all key sizes, mark key points with greek letters (α β γ δ).
draw a house (rectangle 8×6cm, brown outline): top with shaded isosceles triangle roof (height 3cm, light gray fill), left middle with square window (2cm side, blue outline), lower middle with rectangle door (2×4cm, black outline). inside the house, draw a solid red heart (4×4cm, full fill) on the right of the window. next to the heart, draw a simple puppy (≤3cm tall, black outline) with blue round glasses on its face. mark greek letters α β γ δ at roof apex, window center, heart top, puppy head respectively.

Explanation:

This problem is about creating a geometric drawing following specific rules. It involves using geometric shapes (rectangle, triangle, square) with given dimensions, coloring, labeling key points with Greek letters, and adding a heart and a puppy. The main subfield here is Geometry (under Mathematics) as it focuses on geometric constructions, measurements, and labeling of points/shapes.

Answer:

The subfield that best applies is Mathematics - Geometry.
