All side edges of the prism are equal in length. The shape of the top and bottom of the prism are the same, and the shapes of the sides are bothIt is a parallelogram. namilaboerjijin https://padlet.com/namilaboerjijin/r0oau3cqno8xooo2/wish/672251575 2020-08-07 08:11:44 UTC https://padlet.com/namilaboerjijin/r0oau3cqno8xooo2/wish/672251575 (3) Are the cuboid and cube is prisms? namilaboerjijin https://padlet.com/namilaboerjijin/r0oau3cqno8xooo2/wish/672252226 2020-08-07 08:13:28 UTC https://padlet.com/namilaboerjijin/r0oau3cqno8xooo2/wish/672252226 (4) Classification of prisms.People usually divide prisms into triangular prisms, quadrangular prisms, pentagonal prisms, and hexagonal prisms according to the number of sides of the bottom graphic.The shapes of their bottom graphics are triangles, quadrilaterals, pentagons, and hexagons.It should be noted that prisms are divided into straight prisms and oblique prisms. All discussions in this book are straight prisms. namilaboerjijin https://padlet.com/namilaboerjijin/r0oau3cqno8xooo2/wish/672252568 2020-08-07 08:14:33 UTC https://padlet.com/namilaboerjijin/r0oau3cqno8xooo2/wish/672252568
