  1. Similar Triangles – With Trigonometry – Card Match B In this activity students work individually or in groups to match similar triangles. Students may or may not find the angles for each pair of triangles. ‘Quick Cut’ – Choose the questions/slides you wish to use and delete others. Sets of questions can then be easily guillotined to save time. One-sheet sets of cards are also included for students to cut out themselves.

  2. Printing To print handouts from slides - Select the slide from the left. Then click: File > Print > ‘Print Current Slide’ To print multiple slides - Click on a section title to highlight all those slides, or press ‘Ctrl’ at the same time as selecting slides to highlight more than one. Then click: File > Print > ‘Print Selection’ To print double-sided handouts - Highlight both slides before using ‘Print Selection’. Choose ‘Print on Both Sides’ and ‘Flip on Short Edge’.
