Warm-Up 1. ) Create a 2″ segment named AB 2.) Create a 40º angle named angle CDE 3.) Create and label a diagram of two congruent triangles GHI and XYZ. Key ideas from the warm-up: Label with not just the … Continue reading

## 11/8/16- Unit 2 Embedded Assessment 1

Students took EA2.1, starting individually for 15 minutes and then working in their groups.

## 11/7/16- Transformations Review and Triangle Congruence

We reviewed some key ideas about transformations. key-ideas-for-ea2-1 transformations-review-questions We then took new notes about congruent shapes: Congruent Shapes Two shapes are congruent if all of their corresponding parts are congruent. We identify corresponding parts of two triangles using descriptive … Continue reading

## 11/4/16- Congruence through Transformations

Congruent Shapes Two shapes are said to be congruent if there is some rigid transformation or composition of rigid transformations that can map one shape to the other. We practiced this idea on SpringBoard pages 134-136: 1-10 and p. 138: … Continue reading
