This lesson is the fifth of six lessons in the Math 1 Geometry Unit.
In this lesson, the students will learn how to:
~classify triangles as acute, obtuse, or right given their vertices,
~classify triangles as scalene, equilateral, or isosceles given their vertices,
~calculate the perimeter and area of triangles given their vertices.
The download for this lesson includes guided notes (with examples and class work problems), an answer key to the guided notes, a SMART Notebook presentation that corresponds with the guided notes and a "Ticket out the Door" that can be used as a formative assessment.
