Hello peanut gallery! The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles . 1 = 1. The cosine of the angle = the length of the adjacent side. If I want to draw a triangle, for example, with its data (1,22,20), then '1' gives the order among all data points (different triangles), the triangle should be drew in most left; "22,20" gives the "bottom-tip" of the triangle along the y-axis. Area is 2-dimensional like a carpet or an area rug. A triangle is a three-sided polygon. Multiply the base times the height. 3 inches x 2 = 6 inches; 6 inches + 1-3/4 inches = 7-3/4 inches; Your contrasting squares would each be 7-3/4 x 7-3/4 inches. (Your total is now 3⅞”). To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2. In this case we find the third angle by using Angles of a Triangle, then use The Law of Sines to … See Solving "AAS" Triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram. For your practice HST, let's make 3 x 3 inch HST units. We’ve come full circle and back to the positive direction. For example: Let’s say you want to make 3” finished half-square triangles.
