Plane and Solid Figures

(for more information visit www.georgiastandards.org)

M2G1 Students will describe and classify plane figures (triangles, squares, rectangles, trapezoids, quadrilaterals, pentagons, hexagons, and irregular polygonal shapes) according to the number of edges and vertices and the sizes of angles (right angle, obtuse, acute).
M2G2 Students will describe and classify solid geometric figures (prisms, cylinders, cones, and spheres) according to such things as the number of edges and vertices and the number and shape of faces and angles.
a. Recognize the (plane) shapes of the faces of a geometric solid and count the number of faces of each type.
b. Recognize the shape of an angle as a right angle, an obtuse angle, or an acute angle.
M2G3 Students will describe the change in attributes as two and three-dimensional shapes are cut and rearranged.
