Isosceles Triangle.
An isosceles triangle.
A scalene triangle
One is a three-sided figure with two sides of equal length; the other is a four-sided figure with one pair of parallel sides.
A square is 4 sided with sides of equal length and angles of equal measure A triangle is a three sided CLOSED figure
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
The definition of a scalene triangle is: A three-sided figure (triangle) with no two sides equal.
A three-sided figure with two equal sides is called an isosceles triangle. In an isosceles triangle, two sides are of equal length, while the third side may be a different length. The angles opposite the equal sides are also equal in measure. Isosceles triangles exhibit unique properties in geometry, such as having a line of symmetry along the axis of the unequal side.
A flat three sided figure is a triangle.
Isn't that an Isoceles Triangle?
A three-sided figure where all three sides are the same size.
A three-sided polygon is called a triangle. It consists of three straight sides and three angles, with the sum of the interior angles always equal to 180 degrees. Triangles can vary in shape, including equilateral (all sides equal), isosceles (two sides equal), and scalene (all sides of different lengths). The simplest form of a triangle is a closed figure with three vertices connected by straight lines.
Such a figure is called a square. Actually only one right angle is enough to force the the other angles to be right, and if three sides are equal, that forces all sides in such a figure to be equal. Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.
