O1: Measure the interior angles and the length of each side of a triangle. The worksheet generates eight random triangles..keep clicking the 'change' button until all the triangles are a reasonable size and don't overlap.

Measuring angles and length
Years 7 (age 11-12)

O2: Measure the interior angles and the length of each side of a quadrilateral. The worksheet generates six random quadrilaterals..keep clicking the 'change' button until all the quadrilaterals lie within the border and don't overlap.

Construct triangles
Years 7 (age 11-12)

O4: Given two sides and the included angle (SAS)
O5: Given two angles and the included side (ASA)
O6: A mixture of the above

Measure and construct Christmas trees

O7: Measure a Christmas tree

A Christmas tree is shown on the worksheet. The task is to measure the length of each line and size of each angle. (The lengths given on the answer sheet might not be accurate! Blame the printer!)

O8: Construct a Christmas tree

The reverse of the above worksheet: the measurements are given, the task is to accurately construct the Christmas tree. When the worksheet is loaded the answer sheet showing the tree is visible, the pupil page just shows the dimensions.
