THE 30°60°90° TRIANGLE THERE ARE TWO special triangles in trigonometry One is the 30°60°90° triangle The other is the isosceles right triangle They are special because, with simple geometry, we can know the ratios of their sides Theorem In a 30°60°90° triangle the sides are in the ratio 1 2 We will prove that below The triangle is a special right triangle, and knowing it can save you a lot of time on standardized tests like the SAT and ACT Because its angles and side ratios are consistent, test makers love to incorporate this triangle into problems, especially on the nocalculator portion of 30 60 90 triangle rules and properties The most important rule to remember is that this special right triangle has one right angle and its sides are in an easytoremember consistent relationship with one another the ratio is a a√3 2a
