A quadrilateral is "guaranteed" to be a parallelogram if
(a) the opposite side are parallel, or
(b) any line segment perpendicular to one side and intersecting the opposite side is also perpendicular to the opposite side, or
(c) any line segment perpendicular to one side and intersecting the opposite side has the same length as any other such perpendicular line intersecting the opposite side (sometimes vaguely expressed as "opposite sides are everywhere equidistant"), or
(d) the angles at the two ends of any side add up to 180 degrees.
it is anisogamy
milage, interior condition, exterior condition
This is called the locus.
The answer is Yes and No both! In the condition ASS, expand it as Angle-Side1-Side2. Now, Two triangles are said to be congruent if and only if there is only a single triangle which can be constructed through those given conditions.For e.g. in SSS congruency only a single triangle can be constructed through given three sides in the congruency condition. Here, if a triangle is constructed with a base side(Side1) and base angle (Angle), then the condition is based on the length of the third element (Side2). If side 2 is longer than side1, then two triangles are possible, but not if side2 is longer than Side1. So, it depends on on second Side of the congruency condition.
Continuity in mathematics is the first derivative equal to zero or the Boundary condition.
A description that states a quadrilateral has one pair of opposite sides that are both equal and parallel does not guarantee that it is a parallelogram. While this condition is sufficient for proving that a quadrilateral is a parallelogram, it is not necessary; other configurations might exist where a quadrilateral meets this condition without being a parallelogram. Other descriptions, such as having both pairs of opposite sides equal or both pairs of opposite angles equal, would guarantee it is a parallelogram.
The condition for being a parallelogram is that both pairs of opposite sides must be parallel.The condition for being a parallelogram is that both pairs of opposite sides must be parallel.The condition for being a parallelogram is that both pairs of opposite sides must be parallel.The condition for being a parallelogram is that both pairs of opposite sides must be parallel.
at least one pair of opposite sides is parallel
Yes, a quadrilateral ABCD can be a parallelogram if angle D plus angle B equals 180 degrees. In a parallelogram, opposite angles are equal, and consecutive angles are supplementary (their sum equals 180 degrees). Therefore, if angle D and angle B are supplementary, it is consistent with the properties of a parallelogram. Thus, the condition does not contradict the definition of a parallelogram.
A parallelogram is any quadrilateral in which both sets of opposite sides are parallel, or will never intersect. Squares and rectangles (both quadrilaterals) satisfy that condition, and so would rhombus.
That it has 4 sides and a pair of parallel sides of different lengths
NO. A trapezoid cannot be a rectangle. If a parallelogram has one right angle then it is a rectangle. A trapezoid doesn't satisfy this condition because a trapezoid is a quadrilateral with exactly one parallel side which means that it doesn't have a right angle.
A rectangle is a parallelogram where all internal angles are equal at 90°
Yes, a square is a special type of parallelogram. Every square has two pairs of parallel sides, which is the condition for being a parallelogram.
The quadrilateral described is a rhombus. A rhombus has all four sides of equal length and opposite angles that are congruent, with adjacent angles being supplementary. This means it can have two distinct pairs of congruent angles, satisfying the condition mentioned. Additionally, a rhombus can be considered a special type of parallelogram.
No, none of rectange is parallelogram, as to a polygon has to be parallelogram when it follows following conditions: It must have 4 sides, and the oppostie side have to parallel to each other. As no triangle fulfill this condition so no triangle is parallelogram.
In Euclidean geometry, a parallelogram is a simple (non self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean Parallel Postulate and neither condition can be proven without appealing to the Euclidean Parallel Postulate or one of its equivalent formulations.A simple (non self-intersecting) quadrilateral is a parallelogram if and only if any one of the following statements is true;Two pairs of opposite sides are equal in lengthOne pair of opposite sides are parallel and equal in length.source:From Wikipedia, the free encyclopedia;Subject: Parallelogram.
