Shape Perimeter Quiz Master

## Description

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 circle's 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 user's' problem solving capability.
\- Universal App - works on iPhone and iPad devices.
