Quiz · Geometry & Shapes
Perimeter is the fence around a shape; area is the grass inside. Measure rectangles, L-shaped rooms, triangles, parallelograms, trapeziums and circles, then put it to work pricing a new carpet.
Name flat shapes from their pictures, find missing angles in triangles and on parallel lines, and measure area and perimeter.
