In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
A Triangle
No
A shape that is not a quadrilateral is a triangle. Triangles have three sides and three angles, while quadrilaterals have four sides and four angles. Other examples of shapes that are not quadrilaterals include circles, pentagons, and hexagons. Each of these shapes differs in the number of sides and angles they possess.
A shape with 12 sides and 12 angles is known as a dodecagon. In geometry, a dodecagon can be regular, meaning all sides and angles are equal, or irregular, where the sides and angles can vary. Regular dodecagons have internal angles measuring 150 degrees each.
Yeah.
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
A Triangle
Regular shapes are shapes where all the sides and angles are equal. One example of a regular shape is a square because all the sides are the same and all the angles are 90 degrees.
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
Irregular polygons, curves, open shapes all lack congruence of angles and sides.
No
Polygons
All polygons have the same number of sides as angles. So if there are 12 sides, thereare 12 angles.
A 6 sided hexagon has 6 angles that add up to 720 degrees
