Today's topic is all about geometer sketchpad. We found that it is really enjoyable and useful to be used in school. It makes geometry lesson easier for people to learn and love it. Besides, it easy to be used once you install it in your pc.Brilliant!!! We wonder where we want to put our geometry set since we have this kind of software????????????? Actually, this is the alternative way for teachers to teach about this topic and at the same time, it is the interesting topic for pupils to learn.
