Visualizing Problems with Sketches

Draw It Out!

Whenever possible, draw a diagram of the problem. Label all sides, angles, and known values. Visualization helps you see which trigonometric ratios or identities to use and reduces careless mistakes.

Examples

  • Drawing a triangle and marking the angle of elevation and known distances.

  • Sketching the unit circle to understand angle measurements and coordinates.
