MTH 085 - Applied Geometry for Technicians

4 Credit(s)

MTH 085 Applied Geometry includes the following: linear, square, and cubic units, dimensional analysis in metric and US customary measures, problem solving, angle measure, properties of pairs of angles formed by system of parallel, perpendicular, and transversal lines; perimeter and area of polygons and circles; surface area and volume of solid figures such as prisms and pyramids; similarity, ratio, and proportion, right triangle trigonometry.  Oblique triangle trigonometry is an optional topic. Some algebra topics from MTH 075  will be applied. The course will emphasize clear communication of mathematical results. Application problems are realistic with some data to be collected, analyzed, and discussed in group setting with results submitted in written form.

Prerequisite: MTH 075  completed with a grade of “C-” or better within the past two years or placement by the College’s Math Placement Process.
