Divide the length of the shortest side of the main triangle by the hypotenuse of the main triangle. Finding the measurement of the third side of a triangle when you know the measurement of the other two sides only works if you have a right triangle or the measurement of at least one other angle. A triangle is a polygon with three edges and three vertices.
In an equilateral triangle like S U N below each height is the line segment that splits a side in half and is also an angle bisector of the.
32 length width. Thus the other side length is. To find the length of the missing side you can either use the pythagorean theorm or realize this is a case of a special right triangle with sides. A c sina or a c cosv b c sinv or b c cosa Given angle and one leg.
