Identifying Similar Triangles Projector Resources

Are these Mathematically Similar?

Checking for Similarity Are any of the triangles ABC, CEF and ACD mathematically similar?

Working Together Take turns to: Select a diagram, and decide whether or not the two triangles are similar, not similar, or ‘it cannot be determined’. Explain your reasoning. Fill in as many angles as you can. Your partner must challenge your explanation if they disagree or describe it in their own words if they agree. Once agreed, glue the diagram onto the poster and write your explanation in pencil next to it. Continue to take turns until all the diagrams are sorted.

Sharing Work One person in your group record your results on your mini-whiteboard and then go to another group’s desk and check your work against theirs. If there are differences, ask for an explanation. If you disagree, explain which column you think is correct. If you have categorized diagrams in the same columns, compare your methods and check that you understand each others’ explanations. If you are staying at your desk, be ready to explain the reasons for your group’s decisions.
