framing square angles

A square is a rectangle with a pair of its consecutive sides equal. Since square is a rectangle, each angle of a rectangle is a right angle and AB=DC, BC=CD. Thus AB=BC=CD=AD. Each of the four angles of a square is a right angle..

(a) Write 0, 1, 2, 3, 4 over each column as shown above. (b) Divide each number by 4 and take the square root. The values obtained are sine ratios. (c) Write these ratios in reverse order and you obtain the cosine ratios (sin A = cos B if A + B = 90 o ) (d) Divide each sine ratio by cosi..
