Lesson Excerpt
Geometry is the study of the parts, including points, angles, lines, shapes, and surfaces. Before they can be examined or measured, it is important to understand the parts of geometric objects.
There are many parts to these objects that you may already recognize. You may or may not know their names already. There are other parts you have seen just by looking at basic shapes. You may not even know these parts have names at all!
Geometric Shapes
Shapes are one of the basic parts of Geometry. Can you think of all the different shapes you can identify?
You may already know what a circle is. You may not know everything about what a circle can do. By understanding the parts of a circle, you can figure out the size, circumference, diameter, and radius of the circle. Other shapes have lengths, widths, heights, areas, and perimeters. Identifying specific parts can tell you a lot about a shape!
First, let us refresh our memory on the basic definition of each shape.
Triangles
A triangle is a threesided figure with three corners.
