Transformations and Properties in Geometry

Mr. Taylor introduces Unit 5, focusing on transformation and congruency. He explains key vocabulary such as transformation, pre-image, image, and translation, emphasizing translation as a type of isometry. Using triangle ABC, he demonstrates how translation works, highlighting the importance of understanding vertices and motion. The video concludes with a discussion on orientation and reflection, noting that orientation remains unchanged during translation.
