Sketch orthographic and isometric projections.
DefinitionSketching should include
- using sketching techniques to sketch standard projections
- using simple engineering drawings as examples.
- using basic technical drawing instruments
- using basic technical drawing techniques to draw standard projections
- using drawing instruments in accordance with standard procedures.
- What are the three primary views used in multiview drawings?
- What is orthographic projection? Why is it important to identify the front view of an object?
- How is the front view of an object identified?
- Why are pictorial drawings used?
- What is the isometric axis, and why is it important?
- What are non-isometric lines? What are some examples?
- What are the steps in drawing a pictorial view from a multiview drawing?

The student will solve problems involving symmetry and transformation. This will include
- investigating and using formulas for determining distance, midpoint, and slope;
- applying slope to verify and determine whether lines are parallel or perpendicular;
- investigating symmetry and determining whether a figure is symmetric with respect to a line or a point; and
- determining whether a figure has been translated, reflected, rotated, or dilated, using coordinate methods.
The student will apply the concepts of similarity to two- or three-dimensional geometric figures. This will include
- comparing ratios between lengths, perimeters, areas, and volumes of similar figures;
- determining how changes in one or more dimensions of a figure affect area and/or volume of the figure;
- determining how changes in area and/or volume of a figure affect one or more dimensions of the figure; and
- solving problems, including practical problems, about similar geometric figures.
