The Unit Circle and Special Triangles
9th - 11th CCSS: Designed
Students identify the properties of right triangles. In this geometry lesson, students identify the different ratios and parts of a Unit Circle. They use the unit circle as an aid in finding parts of a special triangle and trig identities.
Perimeter and Area of Polygonal Regions in the Cartesian Plane
9th - 12th CCSS: Designed
How many sides does that polygon have? Building directly from lesson number eight in this series, learners now find the area and perimeter of any polygon on the coordinate plane. They decompose the polygons into triangles and use Green's...
