Angle A (or θ) = a = 1, b = , and c = 2

Solving Right Triangles

Definitions

Sine - the ratio of the length of the side opposite an angle to the length of the hypotenuse

Cosine – the ratio of the length of the side adjacent an angle to the length of the hypotenuse

Tangent – the ratio of the length of the side opposite of an angle to the length of the side adjacent to that angle

Page 4: Bellringer Angle A (or θ) = a = 1, b =, and c = 2

Ratios

• These ratios are the same for every triangle• The sin(50°) is the same ratio regardless of the

size of the triangle, this is what lets us solve for all sides and angles of a triangle

Triangles

We use capital letters(A, B, C) to label angles

And we use lower-caseletters (a, b, c) to label sides
