Demonstrate understanding of similarity of 2-D shapes.
[C, CN, PS, R, V]
| (a) |
Observe and describe 2-D shapes, relevant to self, family, or community, that are similar. |
| (b) |
Explain the difference between similarity and congruence of polygons. |
| (c) |
Verify whether or not two polygons are similar. |
| (d) |
Explain how ratios and proportionality are related to similarity of polygons. |
| (e) |
Draw a polygon similar to a given polygon and explain the strategies used. |
| (f) |
Solve situational questions involving the similarity of polygons. |
| (g) |
Identify and describe situations relevant to self, family, or community that involve scale diagrams and explain the meaning of the scale factor involved. |
| (h) |
Explain how scale diagrams are related to similarity, ratios, and proportionality. |
| (i) |
Draw a diagram to scale that represents an enlargement or reduction of a given 2-D shape and explain the strategies used. |
| (j) |
Explain how to determine the scale factor for a given 2-D shape and an enlargement or reduction of the shape. |
| (k) |
Verify whether or not a given diagram is a scale diagram of a 2-D shape and, if it is, identify the scale factor for the diagram. |
| (l) |
Solve situational questions involving scale diagrams and scale factors. |
