Optical Instruments Optical instruments processes light waves to enhance an image for viewing or analyze light waves to determine number of characteristic properties. The very first optical instruments were telescopes and microscopes used for magnifications of images. Mirrors and lenses find their applications in very many walks of life. Since the days of Galileo, these […]

Introduction We can identify different quadrilaterals based on the properties sides, diagonals and angles. Quadrilaterals are made up of ten parts. However, to construct them, you do not need to know the measurements of all of them. In case of special quadrilaterals, like the rectangle, just two measurements, the lengths of its adjacent sides are enough to construct it. A kite can

Topic: FACTORIZATION: COMMON FACTORS a(b + c) = ab + ac The reverse process, ab + ac = a(b + c), is called taking out the common factor. Consider the factorisation of the expression 5x + 15. Clearly, 5x = 5 X x 15 = 3 X 5 ∴ HCF = 5 Thus 5x + 15 = 5 X x + 3 X 5 = 5(x + 3)
