Instructions: Practice drawing triangles. Triangles consist of three straight lines meeting at three angles.

Materials: Ruler, drawing paper, drawing implements such as pencils, fine-tipped pens or markers, or charcoal.

Keywords: Triangle, angles

Step 1: Draw a triangle as shown below. Use a ruler if desired.

Step 2: Add more triangles to your drawing, however as you wish.

Step 3: With a fresh piece of paper, draw anything you wish, but incorporate at least one triangle into your artwork. Use glue, scissors, colored paper, markers, paint, or anything else you desire to create your artwork.

See below the painting 'Portrait of Adele Bloch-Bauer I' by Gustav Klimt. Look closely at the painting to find the triangles. Next find the circles, squares, rectangles, and eye shapes in the painting.
