Angles in a Triangle
Show that when you move the points of a triangle the angles always sum to 180o
Angle in a Semicircle
Show that the angle drawn in at the circumference from either ends of the diameter is always 90o.
Make a poster showing the basic polygons and their names. For example
Move intersecting parallel lines to show that alternate, vertically opposite and corresponding angles are always equal.
Accurately construct the perfect Tangram puzzle after first calculating the required lengths and angles.
Research different ways of finding the centre of a triangle. Investigate the conditions under which at least two of the following coincide:
Show the relationship between sine and cosine in a dynamic unit circle.
Find the transform tools then make dynamic diagram showing what each type of transformation looks like.
