P5/P6 Math: Angles in Triangles and Square Overlapping

Learning Angles begins in P3 where students learn that the right-angle exists in squares and rectangles and in between 2 perpendicular lines.

Once they reach P5, the students will learn more about triangles and parallel lines (within 4-sided figures).

Such questions involving both squares and triangles in a figure will require several rules(concepts) in order to find out the angle needed.

A "set square" is actually a "triangle"
