The sides of a 30-60-90 triangle are in the ratio 1:2:. The smallest side (1) is opposite the smallest angle (30°). The largest side (2) is opposite the largest angle (90°)
Tangent is opposite side divided by adjacent side in right triangles. Tangent is one of three most common trigonometric functions. Tangent is written as 'tan' and often remembered as SOH
Trigonometry deals with relationships between triangle sides and angles. Right-angled triangle has one 90° angle. Six basic trig ratios: Sin, Cos, Tan, Cosec, Sec, Cot
Trigonometry studies right-angled triangles and their parameters. Concept initiated by Greek Mathematician Hipparchus. Divided into plane and spherical trigonometry. Cosine function finds adjacent sides or hypotenuses
Angle is the space between two rays with the same endpoint. A full circle measures 360 degrees. Polygons have the same number of sides as interior angles
A 30-60-90 triangle is a special right triangle with angles 30°, 60°, and 90°. The angles are in a ratio of 1:2:3. The sides are in the ratio of 1:√3:2
