Isn't that an Isoceles Triangle?
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.
its not possible... a quadrilaterial is defined as a four-sided polygon the only thing that i can think of that has three equal sides but no parallel sides is a equilateral triangle
The primary difference between a square and a triangle is the number of sides each has. The square has four while the triangle has three. Let's look a bit further.The triangle has no restrictions on its shape; its a three-sided figure with line segments connected together. The square on the other hand has four sides of equal length. This will also mean it has four right angles in its interior. A square is a special case of a rectangle, which is a special case of a quadrilateral. Lastly, the term quadrilateral is the general term for a four-sided figure.
A triangle - It comes in three types -the Equilateral triangle - all sides of equal lengththe Isosceles triangle - two sides of equal lengththe Scalene triangle - all sides of different length
Isosceles Triangle.
Equilateral 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 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.
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.
