1 Mat College Mathematics Updated on Nov 5, 009 Chapter 8 Geometry We will discuss following concepts in this chapter. Two Dimensional Geometry: Straight lines (parallel and perpendicular), Rays, Angles (acute, obtuse, straight, vertical, complementary, supplementary), Similar and congruent shapes, Polygons (Triangles (scalene, equilateral, isosceles, right, obtuse angled, acute angled), Quadrilateral (parallelogram, rectangles, squares, rhombus, trapezoids), Pentagons (5 sided polygons), Hexagons (6 sided polygons), Heptagons (7 sided polygons), Octagons (8 sided polygons), Nonagons (9 sided polygons), Decagons (0 sided polygons)), Regular polygons, Circle (radius, diameter, circumference), Area, Perimeter. Geometry of Three Dimensions: Volume and surface area of box, cube, Polyhedron (prism, pyramid, cone), cylinder, sphere. Trigonometry: soh, cah, toa from a right triangle. Triangle: Let a, b, c be the measures of three sides and h be the height from a vertex to the side b of a triangle. Then Perimeter = a b c units, and semi-perimeter s ( a b c)/ units Area = / b h square units. Area (in terms of sides) = s( s a)( s b)( s c) square units, this formula is known as Herron s formula. Quadrilateral: Let a, b, c, d be the sides of a quadrilateral, then perimeter = a Area of parallelogram = base height Area of rectangle = length width Circle: Circumference = r and Area r, we have also circumference diameter Oval (Ellipse): Area = ab, where a and b are the lengths of the semi-major and semiminor axes. Volume and surface area: ox (rectangular solid): Let a, b, c be the length, width, and height of a box. The surface area of the box is equal to S ( ab bc ca) ands the volume is V a b c Volume of a prism or cylinderv A h, where A is the area of the base and h is the height. Surface area of a closed cylinder S rl r Volume of a pyramid or a conev A h, where A is the area of the base and h is the height. Volume of a sphere V r, where A is the area of the base and h is the height. Surface area of sphere S r b c d

2 Mat College Mathematics Updated on Nov 5, 009 Trigonometry: soh, cah toa stands for the following results The right triangle has hypotenuse h, opposite o and adjacent a oposite o Then sin x h o hypotenuse h adjecent a cos x and hypotenuse h oposite o tan x x a adjacent h Important relations in right triangles: Angles are in degrees Different Positive Angles: Acute angle, Right angle, Straight angle, Obtuse angle and Reflex angle Types of Angle Description Example Acute Angle An angle, which is less than 90 degree or less than 60, 0.55,, 6 Right angle An angle equal to 90 degree or is right angle 90 degree or Straight angle An angle equal to 80 degree or 80 degree or Obtuse angle An angle greater than 90 degree but less than 80 degree Reflex angle An angle, which is greater than 80 degree but less than 60 degree 00, 9.55, 00, 9.55, Trigonometric angles Two rays drawn from a common vertex form an angle. One ray of the angle is called the initial side while the other is referred to as the terminal side. The angle formed is identified by showing the direction and amount of rotation between initial and terminal sides. If the rotation of terminal side from initial side is in the counter clockwise direction we call it positive angle. If the rotation is in clockwise direction the angle is negative. Terminal side Initial side Terminal side Vertex

3 Mat College Mathematics Updated on Nov 5, 009 Vertex Initial side Initial side Vertex Initial side Fig a Fig b Fig c Positive angle Negative angle Positive angle Angle measured in degrees The angle from between initial and terminal sides by one complete revolution is equal to 60 degrees, we write as 60, which is equal to right angles. Thus one right angle is equal to 90. On the other hand one straight angle is equal to right angles or / of a complete revolution. Thus one straight angle is equal to80. Terminal side Vertex Terminal side Initial side Terminal side Initial side Vertex Vertex Initial side Fig a Fig b Fig c Right angle Straight angle Complete revolution Angle measured in radians In the radian system of measuring an angle, the measure of one revolution is 60. Thus 80 = right angle, and / 90 = right angle. A central angle is an angle whose vertex is at the center of a circle. If the central angle formed between the rays is equal to the radius of the circle, we call it one radian. / r r / Central angle = radian Relation between degree and radian measures Central angle = radian

5 Mat College Mathematics Updated on Nov 5, 009 Area of a sector of a circle Consider a circle of radius r. If is A measured in radian is the central angle of the circle, then the area of the section O OA is given by Area of section OA r square unit.. The radius of a circle is given 0 cm. Find the area of the section formed by the initial and terminal sides with central angle 0 degrees. Solution: The area of the section is 0 OA r cm 80 Some standard values of sine, cosine and tangent functions: Let us produce a table, which is useful in this case. How do we make the first row: Write successively 0 Divide each number by Take square root The values are for sine function Write sine values from backward for cosine function Divide sine values by corresponding cosine values to get values for tangent function. 0 0 sin 0 cos tan Undefined 5
