Choose the shape to which the given set of properties (sides, angles, lines of symmetry) apply
Identify 2D shapes from their properties
Many regular 2D shapes can be characterized in terms of the length and number of sides, number and size of angles and number of lines of symmetry.
For instance, a shape has 2 pairs of equal length sides, 4 equal angles of 90 degrees and 2 lines of symmetry. Given that it has 4 angles of 90° it must be a regular quadrilateral. Knowing that it has 2 pairs of equal length sides we can deduce that it is a rectangle. This is confirmed by the fact that it has 2 lines of symmetry.
Question 4 of this topic describes a shape with 3 sides, 1 right angle and no lines of symmetry. From the 3 sides you know that it is a triangle. The fact that it has both a right angle and no lines of symmetry mean that it has to be a right angle triangle.
In this topic you are given as question a description of a shape in terms of it's sides, angles and lines of symmetry. You have to decide which shape that description applies to. The shapes that are covered include square, rectangle, different types of triangle, rhombus, parallelogram, kite, pentagon, hexagon, etc.
