How to Draw a Trapezoidal Prism

12 steps · Medium · about 9 min

Draw a trapezoidal prism in 12 easy steps, about 9 minutes. Free, with a printable worksheet.

Each picture adds one red line. Draw that line, then scroll to the next picture. Rub out any dashed helper lines at the end. First up: top and bottom.

Step 1: Top and bottom
Draw a long flat line: start left, stop right. Above its middle draw a shorter flat line.
Tip Keep the 2 lines level, like the floor. The short one sits over the middle of the long one.
Step 2: Slanted sides
Join the ends with 2 slanted lines. Start at each end of the top line, stop at the bottom line.
Tip A trapezoid has 4 sides, and only the top and bottom run the same way.
Step 3: Two big eyes
In the middle of the trapezoid draw 2 big egg eyes. Colour a black dot in each, leaving a shine.
Step 4: Big smile
Leave a gap under the eyes, then draw a wide U smile. Start under one eye, stop under the other.
Step 5: Rosy cheeks
Under the outside of each eye, clear of the smile, draw a small sideways oval for a cheek.
Step 6: The top side
Start at each end of the top line. Slant 2 short lines up right, stop, and join them.
Tip The back line is the same length as the top line in front of it.
Step 7: The right side
Start at the back corner and copy the right slant down. Stop, then slant back to the bottom corner.
Step 8: Sparkles
Draw 2 sparkle stars on each side of the prism, one high and one low.
Step 9: Floor and shadow
Draw a thin flat oval shadow round the bottom of the prism. Add a floor line out from each end.
Step 10: Yellow sparkles and top
Go over your lines. Colour the 4 sparkles and the top side of the prism yellow.
Step 11: Pink cheeks, green front
Colour the cheeks pink. Colour the trapezoid front light green, around the face. Leave the eyes white.
Step 12: Grey shadow, green side
Colour the shadow grey and the right side dark green. Your trapezoidal prism is done!
