I Have to Know by the End of this Lesson

There are some interesting links on the concepts explained in this lesson.

Here you are the IXL site with basic exercises:

- Similar and congruent figures
- Similar figures: side lengths and angle measures
- Congruent figures: side lengths and angle measures
- Congruence statements and corresponding parts
- Congruent triangles: SSS, SAS, and ASA

There are also other sites with questions of higher level.

In this page we look at *plans* drawn to a particular *scale*. Recall that

A *scale* is used to represent real life measurements on the smaller plan.

In this other web you can solve word problems and questions of higher level.

Finally watch the following videos.

First of all you have to listen to “Les Luthiers”.This video is about Thales’ Theorem. It is in Spanish but it is a great video. Les Luthiers must sing it in English.

Being serious, we will finish with this two videos in English, more instructive but less funny!
