Trigonometry (from Greek trigønon, “triangle” and metron, “measure”) is a branch of Mathematics that studies relationships involving lengths and angles of triangles. The study of angles and of the angular relationships of planar and three-dimensional figures is known as Trigonometry. The Trigonometric functions comprising Trigonometry are the Cosecant (cosec ø), Cosine (cos ø), Cotangent (cot ø), Secant (sec ø), Sine (sin ø), and Tangent (tan ø). These Manipulative helps children to do and discover their ideas.. A clinometer is a tool that is used to measure the angle of levation ( Angle from the Ground) in a right angled triangle. This can be used to measure the height of tall things that you can’t possible reach the top of such as flag, poles, buildings, trees etc. (Size : 28cm x 13cm)
