What is symmetry? We explain what symmetry is and how primary-school children are taught to find the line of symmetry and draw lines of symmetry on different shapes. What is symmetry? Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing ...
Are the terms trapezoid and trapezium interchangeable? They are not interchangeable; their usage depends on the regional variation of English being used. 6 Can a trapezoid be symmetrical? A trapezoid can be symmetrical if it has a line of symmetry through the midpoints of its non-parallel sides...
Using the symmetry of pentagon , notice that ≌. Therefore, . Since , , , So since must be greater than . Notice that . Therefore, . Note that since is a regular pentagon, all of its interior angles are . We can say that pentagon is also regular by symmetry. So, all of the ...
