Mrs Lin These are the two most common right triangles For degrees, the ratio is 1 1 √ 2 For degrees, the ratio is 1 √ 3 2 Other concepts to remember are that in any triangle a larger angle corresponds to longer side and bsame angles have the same side lengthA 30 60 90 triangle completes an arithmetic progression 3030=6030 =90 An arithmetic progression is a sequence of numbers in which the difference of any two successive numbers is a constant For instance, 2,4,6,8 is an arithmetic progression with a constant of 2A 30 60 90 triangle is a special type of right triangle What is special about 30 60 90 triangles is that the sides of the 30 60 90 triangle always have the same ratio Therefore, if we are given one side we are able to easily find the other sides using the ratio of 12square root of three This special type of right triangle is similar to the
