Heron's Formula
Young scholars 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...
Curated OER
Composition of Reflections
Students perform reflections and translations of polygons. In this geometry lesson, 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 instructional activity, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.
Curated OER
Orthographic Drawings
Students investigate the creation of three dimensional drawings. In this geometry lesson, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.
Curated OER
Orthographic Drawing
Students investigate orthographic drawings. In this geometry activity, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.
