Focus: measuring and drawing obtuse angles

Choose a set of obtuse angles to draw. You will need a protractor (you can either borrow one from school (or from an older sibling!) if you do not have one).

You can just do one set, one from each set or all of them!

Draw a line. Line up the centre of your protractor on the end of the line. Use the scale which starts on zero.

Set A:

100 degrees

170 degrees

130 degrees

Set B:

95 degrees

135 degrees

165 degrees

Set C:

112 degrees

158 degrees

178 degrees
