Mr. Núñez A trapezoid is a polygon with only one pair of parallel lines. To find the area of a Trapezoid we use the following formula: A = h • (b1+b2) ÷ 2 Example 1: Step 1: Write the formula A = h • (b1+b2) ÷ 2 Step 2: Substitute the variables A = 5 • (8 + 4) ÷ 2 Step … Read more
The area of a Triangle is the number of square units it takes to exactly fill the interior of a triangle. Formula for finding the area of a triangle is: A = (b • h) ÷ 2 Example 1: Step 1: Write the formula A = (b • h) ÷ 2 Step 2: Substitute the variables with the … Read more
The area of a polygon is the number of square units inside the polygon. Area is 2-dimensional and is the space taken up inside a polygon. A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the … Read more
Polyhedrons are 3-dimensional shapes made up of many polygons. polyhedrons have a “first” and “last” name. they get their first name from the base shape, and their last name from whether or not they are prisms or pyramids. Pyramids are polyhedrons whose faces are all triangles and meet at one vertex. Prisms are polyhedrons whose … Read more
