Midline: A midline is a segment connecting two midpoints of a triangle. Session 2 Fundamentals of Measurement Investigate the difference between a count and a measure, and examine essential ideas such as unit iteration, partitioning, and the compensatory principle.
Session 3 The Metric System Learn about the relationships between units in the metric system and how to represent quantities using different units.
Session 4 Angle Measurement Review appropriate notation for angle measurement, and describe angles in terms of the amount of turn. Session 5 Indirect Measurement and Trigonometry Learn how to use the concept of similarity to measure distance indirectly, using methods involving similar triangles, shadows, and transits.
Session 6 Area Learn that area is a measure of how much surface is covered. Session 8 Volume Explore several methods for finding the volume of objects, using both standard cubic units and non-standard measures. The following picture presents formulas used to compute the area and perimeter for common geometric shapes like circle, triangle, square, rectangle and various polygons. An irregular shape has sides of different length. Calculating area on these shapes involves breaking the shape down into common shapes like squares, rectangles, triangles and circles.
This is because these shapes all have set formulas for calculating their area. Being able to see the shapes within shapes is the key to calculating the area of irregular shapes. After finding the area of each shape add them to get the total area.
In the case of perimeter of irregular object just measure the length of each side and add them up. Share this comparison:. If you read this far, you should follow us:.
