Aug 12, 2022 · In geometry, all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions. Below is line AB or, in geometric notation, \(\overleftrightarrow{AB}\).
Nov 4, 2024 · In other words, lines that bend or are not composed of straight line segments are considered curved lines. The arched shape of a rainbow or a parabola are examples of curved lines. Curved shapes are composed of continuous curved lines. For example, a circle, ellipse and oval are all curved shapes.
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.

An isosceles triangleis a type of triangle where two sides or legs are equal or congruent to each other. The angle between these legs or sides are is called a vertex angle. The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite to the congruent sides are also congruent. Conversely, if the two a...
An equilateral triangle is a triangle in which all three sides are equal along with the angles being equal. The value of each angle of an equilateral triangle is 60 degrees therefore, it is also known as an equiangular triangle. The equilateral triangle is considered as a regular polygon or a regular triangle as angles are equal and sides are also ...
A scalene triangle is a triangle with all three sides of different lengths, and all three angles of different measurements. However, the different measurements don't affect the sum of all the interior angles of the scalene triangle. The sum of the three interior angles always adds up to 180 degrees, which satisfies the angle sum propertyof the tria...

Notice how they appear as sets: the lines with one feather are parallels, and the lines with two feathers are parallel. A "box" at the point of intersection indicates the lines are perpendicular. This "box" represents the presence of a right angle (just as it did in the right triangle).
