Triangles with 3 Common Measures

Open Up Resources 40 min(s)

In this lesson, students examine sets of triangles in which all the triangles share 3 common measures of angles or sides. Students learn to recognize when triangles are "identical copies" that are oriented differently on the page, and when they are different triangles (meaning triangles that are not identical copies). Recognize that changing the relative order of the sides and angles often makes different triangles. Learning targets: students understand that changing which sides and angles are next to each other can make different triangles.
