Understanding Elementary Shapes. All the shapes we see around us are formed using curves or lines. We can see corners, edges, planes, open curves and closed curves in our surroundings. We organise them into line segments, angles, triangles, polygons and circles. We find that they have different sizes and measures.
In mathematics—namely geometry—and in real life, geometric shapes are two or three-dimensional figures that can be recognized and categorized based on a specific outline/boundary and other attributes including curves, lines, and angles.
A Detailed Lesson Plan in Mathematics 2 - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free. This lesson plan outlines a mathematics lesson on identifying straight and curved lines, and flat and curved surfaces on 3D objects.
Straight lines do not bend or wave and include horizontal, vertical, and diagonal lines. Curved lines are bent and not straight. The document discusses different types of lines, provides examples of straight and curved lines, and emphasizes that lines are important for differentiating objects.
After establishing a careful definition, we will see how the geometry of a curve can be expressed through measurements like curvature, a key building block to defining the curvature of higher-dimensional structures in future chapters.

Remember the µ ( of a 3D shape are 2D shapes. Where 2 surfaces meet is called the edge . The point where 2 or more surfaces meet is called the À Æ.
