The document discusses congruence and similar shapes in geometry. It defines congruence as two shapes being the same size and shape, even if reflected or rotated, while similar shapes have the same angles but different side lengths. The success criteria are being able to rotate, reflect, and identify congruent shapes. Students are instructed to draw congruent and non-congruent shapes, cut them out, have a partner sort them, and explain their reasoning.
Congruence ppt 2014
- 1. Congruence Success Criteria: Able to rotate and reflect shapes Know the meaning of congruency Able to identify congruent shapes 10/09/2014
- 2. Similar Shapes Two shapes are said to be similar to each other if one is an enlargement of the other. Angles stay the same, side lengths change What do you notice about the length of the sides? What do you notice about the size of the angles?
- 3. Congruence Two shapes are said to be congruent if they stay the same shape and size The shapes may be a reflection of each other, or be rotated or translated Angles and side lengths are the same
- 4. Draw two columns into your workbooks: Congruent Shapes Non-Congruent Shapes
- 5. Draw the following shapes into appropriate columns.
- 7. Your turn 1. On coloured paper, create four different Congruent shapes and four different Non-congruent shapes. 2. Cut them up 3. Give your shapes to a partner to place as Congruent or Non-congruent. 4. Paste your new shapes into your book and explain why each shape is Congruent or Non-congruent
