In this activity the student will explore the Law of Sines, a theorem involving sine ratios that applies to all triangles.
Before the Activity
Download the attached .Doc or .PDF documents and the TI_Nspire document.
You will need to copy the .tns document to students' handheld before the exploration.
Read activities in advance.
During the Activity
Classroom management tips
Be prepared to guide students during the exploration.
Encourage students to look for patterns, make connections, and share their findings during the exploration.
After the Activity
Assessment and evaluation Evaluate students' conjecture written on page 1.4 of their TI_Nspire document.
Make students write about their findings and support their findings in observations done during the exploration.
Students can use the law of sines to find the sides lengths and angle measures of a triangle.
Students can determine the area of a triangle given side-angle-side information
Connections to other content areas to explore: sail makers can use sine ratios to determine the amount of fabric needed to make a sail.
