\nAn equilateral triangle is a triangle in which all three sides have the same length and all angles are equal.
\nIn the below figure of an equilateral triangle PQR there are three sides i.e., PQ, QR, and RP are equal and there are three angles i.e., \u2220PQR, \u2220QRP, and \u2220RPQ are equal.
\nTherefore, an equilateral triangle is a regular polygon.<\/p>\n

\nA Square is a quadrilateral that has four equal sides and four equal angles.
\nIn the below figure of a square PQRS there are four sides i.e., PQ, QR, RS and SP are equal and there are four angles i.e., \u2220PQR, \u2220QRS, \u2220RSP, and \u2220SPQ are equal.<\/p>\n![\"square](\"https:\/\/www.worksheetsbuddy.com\/wp-content\/uploads\/2021\/02\/square-2.png\")

\nA polygon is regular when all angles are equal and all sides are equal.
\nIn the below figure of a regular pentagon PQRST there are five sides i.e., PQ, QR, RS, ST, and TP are equal and there are five angles i.e., \u2220PQR, \u2220QRS, \u2220RST, \u2220STP, and \u2220TPQ are equal.<\/p>\n

\nA scalene triangle is a triangle that has all three sides are in different lengths, and all three angles are of different measures.
\nIn the adjoining figure of a scalene triangle PQR there are three sides i.e., PQ, QR, and RS are unequal and there are three angles i.e., \u2220PQR, \u2220RSP, and \u2220SPQ are unequal.<\/p>\n

\nA Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. Each angle is at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square.
\nIn the adjoining figure of a rectangle PQRS there are four sides i.e., PQ, QR, RS, and SP where the opposite sides are equal i.e., PQ = RS, and QR = PS. So, all the sides are not equal to each other.
\nSimilarly, among the four angles i.e., \u2220PQR, \u2220QRS, \u2220RSP, and \u2220SPQ where the opposite angles are equal i.e., \u2220PQR = \u2220RSP and \u2220QRS = \u2220SPQ. So, all the angles are not equal to each other.<\/p>\n

\nAn irregular hexagon is a six-sided shape whose sides are not equal.
\nIn the adjoining figure of an irregular hexagon PQRSTU there are six sides i.e., PQ, QR, RS, ST, TU, and UP are equal and there are six angles i.e., \u2220PQR, \u2220QRS, \u2220RST, \u2220STU, \u2220TUP, and \u2220UPQ are equal.<\/p>\n
