Triangle ABC is an isosceles triangle (base isos angles are equal) 4 of 7 If the opposite side is 10cm and the adjacent side is 8cm, what is the angle? (Use calculator) tan-1(o/a || 10/8) = angle, angle = 51.3 degrees 5 of 7 What is the acronym for finding angles in a triangle? SOH CAH TOA (Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent) 6 of 7 What is "Pythagoras Theorem"? a(squared) + b(squared) = c(squared) 7 of 7
