Articulate how you would find the needed location using an equilateral triangle Lesson 1: Construct an Equilateral Triangle ©2015 Great Minds eureka-math.org Lesson A STORY OF FUNCTIONS M1 GEOMETRY Name _ Date Lesson 2: Construct an Equilateral Triangle Exit Ticket ᇞ ‫ ܥܤܣ‬is shown below Is it an equilateral triangle?
