What shape has five lines of symmetry no right angles or obtuse angles and all sides of equal length?
octagon
What shape has four right angles but only two lines of symmetry?
A rectangle. Obviously the right angles are in the four corners of the rectangle. The lines of symmetry occur across the horizontal and vertical. There are no lines of symmetry on the diagonal.
What shape has 4 equal sides and two lines of symmetry?
a square
What shape has order of rotational symmetry but no lines of symmetry?
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
How many lines of symmetry does an irregular heptagon have?
An irregular heptagon, also known as a seven-sided polygon, may have zero, one, or more lines of symmetry depending on its specific shape. In general, a heptagon can have up to seven lines of symmetry if it is a regular heptagon with all sides and angles equal. However, irregular heptagons have varying side lengths and angles, which can result in different numbers of lines of symmetry. To determine the exact number of lines of symmetry for a specific irregular heptagon, you would need to analyze its unique characteristics and geometric properties.
