Drawing Angles to 180° — Interactive Lesson (Ages 11–14)

Do your students place the protractor and read the wrong scale? This 17-slide interactive lesson teaches drawing angles up to 180° accurately, one clear step at a time.

Drawing Angles to 180° in Year 7–9 Maths

Students learn how to draw an angle of, for example, 70°. They draw a horizontal line, place the protractor with its centre line at the right point, start at 0, mark the angle on the scale and join the vertex to the mark with a ruler. Questions then check the essentials: which tool is most important, what to connect the vertex to the marked point with, and which step comes first.
