Pentagon – Properties In a pentagon the sum of the internal angles is equal to 540°. In a regular pentagon each interior angle measure is 108°, and each exterior angle measure is 72°. A regular pentagon has five axes of symmetry, each one of them passes through a vertex of the pentagon and the middle […]

Lines of symmetry in a regular Rhombus What is a Rhombus? A rhombus is a quadrilateral whose all the sides are of equal in length, opposite sides are parallel and opposite angles are equal. In other words, a rhombus is a parallelogram with adjacent sides of equal length. What is line of symmetry ? The […]

Lines of symmetry in a scalene triangle A scalene triangle has no line of symmetry.

Lines of Symmetry in a Regular Equilateral Triangle What is line of symmetry ? The line of symmetry is the imaginary line where we could fold the image and have both halves match exactly. A shape may have more than one line of symmetry depending on its angles and the lengths of each side. For […]

Lines of symmetry in a regular Decagon Line of Symmetry in a regular Decagon ? If a given line splits a given figure into two identical halves, we say that the line has a line of symmetry or that the figure is symmetrical about the line and line is called a line of symmetry or […]

Lines of Symmetry In Regular Polygons What is line of symmetry? An object is considered to be symmetrical, if when folded or sliced in half, both halves are mirror images of one another. An object is said to have a line of symmetry when one half of it is the mirror image of the other. […]

Alternate Angles: Definition and Types In this tutorial we will learn definition and types of alternate angles. In geometry, alternate angles are a special kind of angles. Alternate interior angles are formed when a transversal intersect two parallel or non-parallel lines. If a straight line intersects two lines, in the same plane at two distinct […]
