How many sides and angles do a polygon have?
Polygon is a two dimensional figure that has three or more sides. Polygons are classified by their number of sides. Three sided is a triangle. A four sided figure is a quadrilateral. A five sided figure is a pentagon and so forth. The number of angles it has is equal to the number of sides.A polygon usaally has 5sides
Can two triangles be congruent with 5 pairs of congruent parts?
Two triangles are congruent if the six elements of one triangle (three sides and three angles) are equal to the six elements of the second triangle and the two triangles have a scale factor of 1. However, in four special cases it is only necessary to match three elements to prove that two triangles are congruent. The matching of four elements is sometimes necessary, and the matching of five elements would put the matter beyond any doubt.
What is the name for a five sided figure?
a pentagon
How many sides on a Pentagon and octagon?
Pentagon ; from #Latin for five(5) , so there are five(5) sides. Similaryl Octagon ; from #Latin for eight(8) , so there are eight(8) sides. Other Latin roots for given numbers. Two -= bi/di Three = tri Four = tetra Five = penta Six = hexa Seven = hepta Eight = octa Nine = nona Ten= deca twenty = dodeca Hundred = centa Thousand = milla.
What is the length of the sides of the perimeter of a regular pentagon that is 42cm?
Assuming five sides of the same length, and a sum of 42 centimetres for all five sides, each side would measure 42/5 = 8.4 centimetres.
