Students can use this resource from Illustrative Mathematics to determine lines of symmetry in triangles.
In this lesson, students will have a brief introduction to creating an app in Code.org’s App Lab. They will then create an app that will determine if three given lengths can form a triangle or not.
This geometry lesson is a remix from Illustrative Mathematics. In this lesson, students identify triangles, quadrilaterals, pentagons and hexagons. Students are also required to make these shapes using manipulatives. https://tasks.illustrativemathematics.org/content-standards/tasks/1506
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use. An additional source is added from VDOE to provide a foundation for identifying polygons and other support related to working with polygons.
