Question in Engineering Statics
Find moment of inertia of a composite shape consisting of a rectangle and two triangles with respect to the x-axis. Shapes rest on the x-axis so the parallel axis theorem is not required.
-
Question in Engineering Statics
Use a table of properties to find the Area Moment of inertia for simple shapes: rectangle, triangle, circle, semicircle, and quarter circle.
The parallel axis theorem is not required for any of these shapes. One situation requires subtracting a triangle from a rectangle however.
Distinguish between centroidal and non-centroidal moments of inertia.

Question in Engineering Statics
Find the centroid of a shape made from a rectangle, triangle, and circle.
-
Question in Engineering Statics
Locate the centroid of a rectangle, triangle, and semi-circle on a coordinate grid.

Question in Transition to university
Differentiate between linear and quadratic sequences and arithmetic and geometric sequences through a series of multiple choice questions. Spot different patterns in sequences like the triangle sequence, square sequence and cubic sequence and then use this pattern to find the next three terms in each of the sequences.

Question in Simon's workspace
This question uses the GeoGebra extension so it can ask the student to create an equilateral triangle. It doesn't matter how they do it, as long as they end up with a polygon with three vertices whose sides are all the same length.

Question in Demos
An example of using the GeoGebra extension to ask the student to create a geometric construction, with marking and steps.
-
Question in Demos
This demonstrates how to construct a JSXGraph diagram in JME code.
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 Cameron's workspace
Finding the lengths and angles within a right-angled triangle using: pythagoras theorem, SOHCAHTOA and principle of angles adding up to 180 degrees.
-
Question in Demos
Three equilateral triangles are divided equally into 3, 4 and 5 parts respectively. Calculate the distance between two marked points.

Question in Andrew's workspace
A question testing the application of the Area of a Triangle formula when given two sides and an angle. In these questions, the triangle is always acute and both of the given side lengths are adjacent to the given angle.
-
Question in Andrew's workspace
Two questions testing the application of the Sine Rule when given two angles and a side. In this question, the triangle is always acute.
-
Question in Andrew's workspace
Two questions testing the application of the Sine Rule when given two sides and an angle. In this question, the triangle is always acute and one of the given side lengths is opposite the given angle.

Question in FME
Draws a triangle based on 2 angles and a side length.
-
Question in FME
Draws a right angled triangle based on a length and an angle.
-
Question in FME
Draws a right angled triangle based on 2 lengths.
-
Question in How-tos
Some clever variable-substitution trickery to randomly pick two sides of a right-angled triangle to give to a student, and ask for the other.
The sides are set up so they're always Pythagorean triples, and the opposite side is always odd.
As ever, most of the tricky stuff is in the advice.
Because this was created quickly to show how to set up the randomisation, there's no diagram. It would benefit greatly from a diagram.
