Mathematics · Geometry · procedural
Draw and measure line segments and angles accurately using ruler and protractor, and interpret scale drawings to extract real measurements
What mastery looks like
- Draw a triangle accurately given two sides and the included angle (SAS)
- Measure angles in a geometric figure to the nearest degree using a protractor
- Read a scale drawing to determine actual lengths, explaining the scale used
Check your understanding
