This notebook covers the properties of various geometric shapes including trapezoids, kites, rhombuses, rectangles, and squares. It includes objectives, examples, and problem-solving exercises for each shape. Students will learn about the properties of these shapes, such as their sides, angles, and diagonals, as well as special properties like parallel sides, perpendicular diagonals, and congruent angles.
