    Congruency in triangles

    Lesson presentations and activities

    • This lesson is for GCSE Higher revision but can be used for a high ability KS3 class. This lesson goes through what is meant by ‘congruency’ and the four conditions that are sufficient to prove that two triangles are congruent. There is also an extension on being able to solve GCSE problems on congruency which will extend their learning to a Grade A.

      Great thank you, answers also included

    • Decide which buildings are free from zombies (shufflers and nibblers) by using knowledge of congruence and similarity to help Deputy Nick Crimes. The PowerPoint has basic animations (the answers basically) as it was exported from Notebook, but I've no doubt you can add some if you like. There's a worksheet if the students need it.

      This is awesome. My Y9's will love this! Thanks so much.

    • A worksheet on powerpoint with answers on the following slide. Match up the congruent triangles, leaving ones which are not. For each match give a reason (eg.SSS). I have included some misconceptions to catch some out and also give possible class discussion points, (and edited the mistake mentioned in the comments)
