This video will be used to re-enforce the relationships between the sides and angles in special right triangles. The video has a catchy song that will help students remember the relationships.
This activity results from the ALEX Resource Development Summit.
In this Desmos activity, students are guided through a series of questions to verify the relationships between the sides and angles of a 30°-60°-90° right triangle and a 45°-45°-90° triangle. This is intended to be a during activity for a lesson on discovering and applying relationships in similar right triangles.
In this Desmos activity, students will explore the special relationships between the sides of a 30-60-90 triangle and a 45-45-90 triangle. This is intended to be a before activity for a lesson on the relationships of special right triangles and their connection to trigonometry.
