Aug 12, 2022 · Two points on a plane determine a line. A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry, all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions.
Key Difference: Geometrical shapes cover all basic shapes like lines, polygons and simple curves. Commonly, shapes are divided into three categories – 1, 2 and 3 dimensional shapes. Shape defines the external boundary or surface of an object. Shapes in context to geometrical shapes lie in the concepts of plane and solid geometry.
In geometry, congruent means identical in shape and size. Congruence can be applied to line segments, angles, and figures. Any two line segments are said to be congruent if they are equal in length. Two angles are said to be congruent if they are of equal measure.
Nov 4, 2024 · A solid shape has volume. Solid shapes are composed of other 2d shapes creating line segments, faces, vertices and edges. Some examples of solid shapes include: Cube; Pyramid; Cone; Sphere; Prism; Curved lines and curved shapes. Curved lines are lines that are not straight.

Congruent sides mean when the line segment of the triangles or the radii of two circles are of the same length and are equal to each other. Congruent sides can be seen in different geometric shapes such as triangles, quadrilaterals, and circles.
