Geometry (Class 11)
Lesson Title
Segments and their Measures
Overview
The warm-up for today marks the beginning of a new series which requires students to use the skills they have been developing related to calculating the length of a segment on order to solve a puzzle. The lesson for the day continues with working with calculating lengths of segments. During the last 50 minutes of class students will be taking their second test.
