An imag e has rotational sym metry if it looks th e sam e when rotated, or tu rn, a certain number of times aroun d a center point. For erample, a triangle, if turn e d three times, will look lik e th e sam e all thr e e times. A four-leaf clover will match itself ...

Can we have a rotational symmetry of order more than 1 whose angle of rotation is (i) 45°? (ii) 17°? If the given angle is a factor of 360°, then the figure will have rotational symmetry of order more than one otherwise not.
The angles of a scalene triangle follow the angle sum property and always add up to 180. Types of Scalene TrianglesA scalene triangle can be classified into three categories:Acute-angled scalene triangle In an acute-angled scalene triangle, each angle of the triangle is less than 90°. In si...

Is a scalene triangle a regular polygon? What polygon is similar to every other polygon of the same name? a) triangle b) parallelogram c) rectangle d) square e) trapezoid. How many angles does a trapezium have? Do all parallelograms have reflectional symmetry?
Irregular polygons could have a few sides that are equal but just not all of them, correct? How many sides do tetrahedral dice have? How do you find the measurement of the angles in a polygon? What is geometry ? A triangle that has three sides that measure 4 inches each and angles th...
Alternatively, we can ‘add a triangle’ to the original graph, which in the expanded graph, is equivalent to adding a six-ring (b). 7.2. Case (ii) In this case, the starting graph is allowed to have multiple edges, but no loops. If we start with a multi-graph that satisfies the...
A plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed polygonal chain or circuit. The name ‘poly’ refers to multiple. An n-gon is a polygon with n sides; for example, a triangle is a 3-gon polygon. ...
