If even one side (and therefore, one angle) is different, the decagon is irregular. The sides and angles of this decagon are not equal, making it an irregular decagon. Two polygons are said to be congruent if their sides and angles are equal. Congruence for regular polygons can be ...

Give a sketch of the angle and the locus of points. Angle Bisector Theorem If a point is on the bisector of an angle, then it is equidistant from the sides of the angle. Prove: ∵OA=OB∠AOD=∠BOD∠OAD=∠OBD=90∘∴△AOD...
It is the sum of all six sides. In the case of a regular hexagon, the formula to calculate its perimeter is 6 × side length. What is an Irregular Hexagon? An irregular hexagon has at least one unequal side and angle when compared to the other sides and angles. There is no definite...
INEQUALITIES Sides/Angles of Triangles Geometry 5.2 Objectives: Learn the Exterior Angle INEQUALITY Theorem To Recognize the LONGEST Side from the Largest Angle To Recognize the LARGEST Angle from the Longest Side A REMINDER about INEQUALITIES If a > b if there exists a positive number c such that...
Properties of a Right TriangleIn geometry, a right triangle is a specific triangle that has one of its interior angles exactly at the right angle. Its longest side is known as the hypotenuse, the side just opposite to an acute angle is called the opposite...
The number of sides of a regular polygon can be calculated by using the interior and exterior angles, which are, respectively, the inside and outside angles created by the connecting sides of the polygon. For a regular polygon the measure of each interior angle and each exterior angle is con...
Octagon Definition: Any polygon which has 8 sides and 8 angles is known as Octagon in Geometry. Octagon Meaning: The word Oct means 8 and gon means sides. Together it is known as an Octagon which is nothing but a polygon made of 8 sides....
