Is one sufficient to define a parallelogram? Parallelogram is it necessary to say opposite sides parallel and congruent? The information is necessary to define it.
Walk around the room to observe what you hear and answer anyĪsk the groups to give their definition of each one and decide if all The trapezoid, the parallelogram, the rhombus, the rectangle, the square,Īnd the kite. They will probably know some of these definitions) by measuring sides, determining Have students in groups of two inĪsk the students to determine a definition of each of these figures ( Lesson plan:įirst the teacher will construct several of the six quadrilaterals being Quadrilaterals on Geometer's Sketchpad for students to explore. Materials Needed: Computer lab with Geometer's Sketchpad program Some Students should alsoīe able to determine which shapes are subsets of others and to make a tree To discuss the properties of these quadrilaterals. Students will be able to identify and define quadrilaterals and be able Mathematical definition of each of these and then investigate to discoverĪll the properties of these figures. These figures on Geometer's Sketchpad, the students will first develop a Trapezoid, parallelogram, rhombus, rectangle, square, and kite. In this lesson students will investigate some special quadrilaterals: Geometry course for pre-service elementary teachers. These lessons ware authored by Debra Kopcso, LSU.
