Acc. Pre Calculus Name _______________________________________ Unit 3 Intro to Trig Date _______________________ Block __________ – Day 1 Right Triangle Trig Review – Over the past couple years, you have been working with Right Triangles. Look over the concepts presented on this paper and practice these on the given problems. ** A RIGHT TRIANGLE is a triangle that contains 1 right angle. The Sum of the angles in any triangle is 1800. The longest side of a right triangle is called the Hypotenuse, the other sides are legs. The Pythagorean Theorem, c2 = a2 + b2, can help you find the length of any side of a right triangle. A Right Triangle can be Scalene(no sides are congruent) or Isosceles,(the legs are congruent). There are 2 Special Case Right Triangles: 45 45 90 and 30 60 90. These two – – – – triangles have special relationships between their side lengths (as shown in the pictures) SOHCAHTOA is an acronym we use to help remember how to use TRIG to solve a right triangle. SOH: Sine = ; CAH: Cosine = ; TOA: Tangent = ** Use all of these concepts on the pages to come to help you review Right Triangles **
