A three-sided figure where all three sides are the same size.
okay, what about it? two of its sides are identical. the third side will be rad 2 times as long as the two identical sides. this is a kind of special triangle, another being an eqilateral (60/60/60) and 30-60-90.
Since an equilateral triangle is also equiangular, all the angles have to be congruent. Because all the angles must also add up to 180 degrees, each angle is 60 degrees.
equilateral means all the sides have the same lenght. An eqilateral triangle has 3 sides all of same lenght.Regular means same side length and same angle measure. So an irregular polygon has either different angle measurements or different side lengths or both.So a regular polygon is equilateral AND equiangular.And irregular one is either not equilateral, not equiangular or neither one.
A convex polygon is a polygon such that no side extended cuts any other side or vertex; it can be cut by a straight line in at most two points Example: A square is a convex polygon, as is an eqilateral triangle. A star shaped polygon is NOT convex. More generally, In Euclidean space, objects are convex if for every pair of points within the object, every point on the straight line segment that joins them is also within the object.
