Geometry and Trigonometry Formulae AI HL only

Geometry is the study of shapes, sizes, and positions of objects in space. It involves the study of points, lines, planes, angles, and figures like triangles, circles, rectangles, and squares. Some common topics in geometry include congruence, similarity, area, perimeter, volume, and surface area. Trigonometry, on the other hand, is the study of the relationships between angles and sides in triangles. Trigonometry is used extensively in many fields, including physics, engineering, and navigation. Some common topics in trigonometry include the trigonometric functions (sine, cosine, tangent, cosecant, secant, and cotangent), the unit circle, right triangles, and the laws of sines and cosines.
