Question in Demos
This question demonstrates how to construct a JSXGraph diagram using JessieCode.
The construction shows a triangle and its orthocentre, circumcentre and centroid. They are always collinear. You can move the vertices of the triangle.

Question in Programming extension
In four parts, the student builds up the definition of a class representing a rectangle. First they write the constructor, then add methods to compute area and perimeter.
In the final part, they must use the methods to write a function which determines if a rectangle's area is larger than its perimeter.

Question in Standard Maths
Students explore the relationship between length and area of a rectangle.
The perimeter of the rectangle is randomised. Students are given 11 different lengths, and asked to compute rectangle width and area for each. They are then asked to graph the function, identify it as a parabola, and estimate the maximum value.
-
Question in Standard Maths
Students are given a diagram with 2 triangles. They are given 2 randomised lengths, and a randomised angle of depression.
They need to compute an angle by subtracting the angle of depression from 90°. Then they need to use the sine rule to calculate a second angle. Then they need to use the alternate angles on parallel lines theorem to work out a third angle. They use these to calculate a third angle, which they use in the right-angle triangle with the sine ratio to compute the third side. They then use the cos ratio to compute the length of the third side.
-
Question in Standard Maths
Students are given 2 right-angle triangles - two ramps of differing steepness up a step, and are asked to find one of a selection of randomly chosen lengths. The height of the step is given - it is randomised. Students are also given either the angle of incline of the steeper ramp or its length, both of which are randomised. They are also given the angle of incline of the shallower ramp, which is also randomised.
-
Question in Standard Maths
The student is given a triangle with one side running N-S. They are given bearings for the other two sides. They are given the length of the N-S side.
The bearings and the length are randomised.
They are then asked to find the area and the perimeter of the triangle.
-
Question in Standard Maths
Students are given the bearings and distances of 2 consecutive straight line walks. They are asked to find the distance from the starting point to the endpoint. They are given a diagram to assist them.
The bearings and distances are randomised (any bearing, distances between 1.1 and 5.). Bearings can be given as either compass bearings or true bearings.

Question in Standard Maths
Students are shown one of 5 different radial surveys and asked to answer one of 8 questions about it.
2 questions ask for the length of a side.
2 questions ask for the value of an angle.
2 questions ask for the area of a triangle.
1 question asks for the land area, and 1 question asks for the land perimeter.
The values are hard coded. In cases where your choice of precision affects your answer, a range of answers is accepted, and a comment is made in the advice to that effect.
