Learn to group triangles according to length of the sides or/and size of the angles. Learn the terms: scalene, equilateral, isosceles and right angle triangles. Learn about external and internal angles. Learn to work out the unknown angles by subtracting the known angles from 180˚.
The angles have the correct measurement so the students can find the sizes of angles by measuring using a protractor.
The use of 12 questions (problems) makes the program compatible with the MiniLUK self checking system. Each page has a grid with answers and a MiniLUK code key.
