Shape Perimeter Quiz Master at Mac App Store analyse

What is the Perimeter of that coloured shape? Shape Perimeter Quiz Master is a multiple-choice based quiz program for Shape Perimeter problems. It provides the user with a variety of coloured shapes and challenge the users to calculate their perimeters. The basic shapes covered by this program include: - Square - Rectangle - Triangle - Parallelogram - Trapezium - Circle In addition to these basic shapes, two complex shapes are also included to provide the users with a greater challenge: - Random Shapes - randomisation of the above basic shapes - Composite Shapes - shapes composed of the basic shapes (e.g. a parallelogram joining a triangle) Hints for calculating perimeters of basic shapes: - Square Perimeter = 4 × a where a = length of side - Rectangle Perimeter = 2 × ( w + h ) where w = width and h = height - Triangle Perimeter = a + b + c where a, b, c are the three sides of the triangle - Quadrilateral (e.g. Parallelogram, Trapezium) Perimeter = a + b + c + d where a, b, c, and d are the four sides of the quadrilateral - Circle Perimeter (circumference) = 2 × π × r where r = radius of the circle. Note, the number π is a mathematical constant, the ratio of a circles circumference to its diameter. It is approximately equal to 3.14159 - Analyse the shape and identify right-angled triangles, use Pythagoras theorem to calculate the hypotenuse. - Pythagoras theorem: for a right angled triangle, a² + b² = c² where a and a are the two adjacent sides of the right angle, and c is the hypotenuse (the side opposite the right angle). App Features: - Shape generation mechanism: all shapes are auto-generated, providing unlimited possibilities. - User option to show or hide the grid lines on the shapes. Turning off the grid lines on the shape objects makes the quiz even more challenging. - Performance monitoring for each shape type. - Built-in Stop Watch to time the users problem solving capability. - Universal App - works on iPhone and iPad devices.
