Constructing Perpendiculars
Students construct perpendicular lines. In this geometry lesson plan, students use a compass and straight edge to do construction. They start from a point to a line.
Curated OER
Constructing Triangles
Students construct triangles. In this geometry lesson plan, students create equilateral triangles. They also construct triangles where the sides are different. They use the lab to create and move shapes around with the Cabri program.

Interior and Exterior Angles of Polygons
Students identify interior and exterior angles of polygons. In this geometry lesson, students add interior and exterior angles of polygons. They use angle theorems to solve the problems.
Curated OER
Heron's Formula
Learners use Heron's formula to calculate the area of a triangle. In this geometry lesson, students use three different methods to solve the area of a triangle. They find and construct the incentor and angle bisector of a triangle.
Curated OER
Composition of Reflections
Young scholars perform reflections and translations of polygons. In this geometry instructional activity, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.
Curated OER
Quadrilateral within Quadrilaterals
Students investigate the properties of quadrilaterals. In this geometry lesson, students solve problems dealing with construction and designs. They work with quadrilaterals, midpoints and parallelograms.
Curated OER
Tessellations
Students create tessellations. In this geometry lesson plan, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.
