Corner Collaboration is a Kagan strategy also called 4 Corners where students work in their home group to solve problems and then at teacher signal, go to pre determined corners to compare answers with a new group and get a different perspective on solving problems.

In this activity, students will find 2 sides of special right triangles: both 45-45-90 right triangles and 30-60-90 right triangles. Students will use formulas to find those missing sides lengths. There are 4 different worksheets with 6 problems each. Each group will get a different version of the worksheet as identified by a musical symbol. I allow about 15-20 minutes for the students to complete (your class may need more) and then when the timer goes off, students go to the corner with the symbol matching their sheet. They can compare answers and discuss any errors.

When the timer goes off again, we meet as a group to discuss any difficult or confusing problems, and this gives me an idea to reteach or move on. Great for promoting discourse in the classroom.

Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.
Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
