![]() ![]() Try drawing a quadrilateral, and measure the angles. interior angles that add to 360 degrees:.Therefore, if every side holds a parallel opposite side it is a parallelogram.(Also see this on Interactive Quadrilaterals) Properties Moreover, a quadrilateral can have parallel opposite sides. A quadrilateral has more properties linked with it than a triangle. Finally, the rotational symmetry order is 2 in parallelograms.Īnswer: A quadrilateral refers to a polygon that has four sides. Further, a parallelogram includes equal opposite angles and does not have symmetry lines. Question 5: What are the properties of a parallelogram?Īnswer: Parallelogram has properties that the opposite sides are parallel and equal. Correspondingly, the distinction between the two sides of a triangle is less than the length of the third side. ![]() Secondly, the sum of the length of the two sides of a triangle is larger than the length of the third side. Question 4: What are the properties of a triangle?Īnswer: The properties of the triangle are that firstly, the sum of all the angles of a triangle (of all types) equals to 1800. Question 3: What are the 7 types of triangles?Īnswer: The seven types of triangles that exist in the math are equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene. A triangle with three equal sides is called as? Question 1: What is a triangle with one angle greater than 90° called? The diagonals intersect at 90° or right angles.Parallelogram has equal opposite angles.Rectangle has a rotational symmetry of 2.The opposite sides are parallel and equal.The diagonals bisect each other at 90° or right angles.Opposite sides are parallel, with all sides being equal.Geometric Properties of Quadrilaterals a) Square Moreover, as per other math books, trapezoids possess only a single pair of parallel sides this is strictly followed in high school level mathematics. It means that this would form a parallelogram if there are two sets of parallel sides, making it a special kind of a trapezoid. According to some math books, a trapezoid holds at least one pair of parallel sides. Quadrilaterals that have a single pair of parallel sides are called trapezoids. ![]() ![]() Furthermore, a rhombus holds four sides of equal length. It is important to note that, rectangles, rhombuses (rhombi) and squares are all parallelograms since their opposite sides are parallel (always). Hence, if every side holds a parallel opposite side, this shape is termed as a parallelogram. In a quadrilateral, one amazing aspect is that it can have parallel opposite sides. There are more properties associated to a quadrilateral as compared to a triangle. We can define quadrilateral as a Polygon that has four sides.
