Assignments in Mathematics Class IX (Term 2) 8. QUADRILATERALS IMPORTANT TERMS‚ DEFINITIONS AND RESULTS l l Sum of the angles of a quadrilateral is 360°. A diagonal of a parallelogram divides it into two congruent triangles. In a parallelogram‚ (i) opposite sides are equal (ii) opposite angles are equal (iii) diagonals bisect each other A quadrilateral is a parallelogram‚ if (i) opposite sides are equal or (ii) opposite angles are equal or (iii) diagonals bisect each other or (iv) a pair of

proved what‚ as the group wanted to keep their findings secret. Unfortunately‚ this vow of secrecy prevented an important mathematical idea from being made public. The Pythagoreans had discovered irrational numbers! If we take an isosceles right triangle with legs of measure 1‚ the hypotenuse will measure sqrt 2. But this number cannot be expressed as a length that can be measured with a ruler divided into fractional parts‚ and that deeply disturbed the Pythagoreans‚ who believed that "All is number

epidemiological triangle focuses on the three primary factors that directly effect the “what”‚ “who”‚ and “where” of diseases (Ferng‚ 2011). One of these factors is the disease agent and its characteristics‚ the host and the host’s vulnerability to the disease‚ and the environment that surrounds the agent and host (Ferng‚ 2011). It is crucial to examine these components and how they interrelate to reach a better understanding of the disease. In one corner of the epidemiology triangle for obesity there’s

The materials I chose to use to build my three structures are toothpicks and small marshmallows. I chose these materials because I thought it would be fun to use with young children. It’s an activity that’s not messy just a little sticky and they can enjoy a sweet treat while working. The toothpicks and marshmallows are both small promoting help with fine motor development. The limit to only two types of materials to work with isn’t to over whelming. Also engaging their ability to think of different

2012 The event that I chose to discuss is Heron’s method that was written about in the three book series called metrica discovered in the period of about 60 AD. His formula for calculating the area of a triangle was one of the formulas which was written about in the books. Heron of Alexandria was also very well known by Hero. Their has been much debate on the birth date and ear of when Heron of Alexandria was alive. First people thought that it was around

This snowflake appeared to be one of the earliest fractal curves. The fractal is built by starting with an equilateral triangle. One must remove the inner third of each side and replace it with another equilateral triangle. The process is repeated indefinitely. The length of each side is one which will help you determine the perimeter of each triangle. With having the perimeter of each triangle‚ the height can be determined so the area can be defined. The height must be determined because to use the formula A=12bh to find the area of

“Platonic Solids”. Till now many breath-taking huge structures are inspired by these polyhedrons. It is also found in nature in micro-organisms‚ crystals‚ molecules and many other forms. Even these solids are made of 2D shapes‚ especially 3 shapes: the triangle‚ the square‚ and pentagon polygons. These 3 simple shapes give those solids a unique symmetry impossible to find in any other polyhedron. Every shape has a concept behind it that affects the eye and brain when subjected to it‚ and imprints this concept
