The units of area are squared (cm2, m2, km2) Area of a rectangle Length x Width Area of a triangle 1/2 x Base x Height Area of a parallelogram Base x Height 1 of 6 Questions Q) Angles in a straight line = ? A) 180 degrease Q) Angles in a circle = ? A) 360 degrease Q) A right angle = ?A) 90 degrease Q) What is the name given to the angle less then 90 degrease? A) Acute Q) What is the name given to the angle more the 90 degrease? A) Obtuse 2 of 6 Quadrilaterals Square All sides are equal All angles are equal Diagonals bisect each other and cross at right angles Rectangle Opposite sides are equal All angles are equal Diagonals bisect each other Trapezium Two unequal sides are parallel Interior angles add up to 180 degrease 3 of 6 Quadrilaterals Parallelogram Opposite sides are equal and parallel Opposite angles are equal Diagonals bisect each other Rhombus All sides are equal Opposite sides are parellel Opposite angles are equal Diagonals bisect eachother and cross at right angles. Kite Two pairs of sides are equal One pair of opposite angles are equal Diagonals cross at right angles 4 of 6 Transformations Translations This means that the shape is moved but still looks exctuly the same A translation is described by a vector. The top number in the vector is the movement(Left or Right.) Positive values move to the right. Negative values more to the left. The bottom number in the vector is the movement (Up or Down). Positive values move up. Negative values move downwards. 5 of 6 Transformation Reflection When a shape is reflected it becomes a mirror image if itself. A reflection is described in terms of a mirror line. Rotations When a shape is rotated it is turned around. The rotation will be clockwise/anticlockwise. Turned - 90, 180, 270, 360 degrease. Enlargement When a shape is enlarged it is made bigger. It has a scale factor, and some have a point were the shape has been enlarged. 6 of 6
