![]() Divide the log of the geometric standard deviation by the geometric mean (NOT. Two or more triangles are said to be congruent when the measurements of the corresponding sides and. We can obtain the same result using logarithms. Side-Side-Side or SSS is a kind of triangle congruence rule where it states that if all three sides of one triangle are equal to all three corresponding sides of another triangle, the two triangles are considered to be congruent. Assume a geometric standard deviation of 1.02 and a geometric mean of 1.08. ![]() Example 1 In this triangle we know: angle A 49 b 5 and c 7 To solve the triangle we need to find side a and angles B and C. A calculation of the geometric coefficient of variation looks like this. Given triangle ABC, with two known sides, BC & AC, and an included angle C between these sides. To solve an SAS triangle use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180 to find the last angle. Also, D divides AB in the ratio 1:2 and E is the midpoint of AC.
