Everyday Geometry
Angles
 The space between two lines that connects at a common point
2 Dimensional Shapes
 Figures that only has 2 dimensions, usually length and width.
Triangles
 2-dimensional (or 2D) figures that has three sides and three
angles
Quadrilaterals
 Figures that have four sides
 Square
 Rhombus
 Rectangles
 Parallelogram
Squares, Rhombuses and
Parallelograms
 Squares have 4 equal sides and 4 right angles
 Rhombuses have 4 equal sides but the angles are not right
 Parallelograms have 4 sides and all their sides run parallel to the
opposite side. All squares, rhombuses and rectangles are
Parallelograms.
 Which one is a Rhombus?
Rectangles
 Figures that have 4 sides and 4 right angles, but 2 sides are longer
than the others.
Pentagons
 Figures with 5 sides
Octagon
 Figures with 8 sides
3 Dimensional Shapes
 Shapes that have 3 dimensions, length, width and depth. Real
world shapes
Cube
 A 3 dimensional (3D) shape that has 6 equal faces
 A face is the flat sides of a 3 dimensional object
