A trapezoid has one pair of parallel sides. All other quadrilaterals have no parallel sides or two pairs of parallel sides.
Yes. Two adjacent sides are equal; the other two sides are also equal between themselves.
Don't take sides, try to calm them both.
Diagonals between two opposite corners, and a vertical line between midpoints of 2 opposite sides, and a horizontal line between midpoints of the other pair of sides.
An Isosceles trapezoid has four sides (is a quadrilateral) with a pair of parallel sides and the other two sides of equal length; whereas An isosceles triangle has three sides with a pair of sides of the same length and the other side a different length.
A square, all four sides are equal length. A rectangle has 4 sides, 2 parallel sides are a different length than the other two. A parallelogram is a rectangle where the two adjoining sides are not at a 90 degree angle to each other, but opposite sides are parallel to each other.
If you literally mean "killing", call the police. But, if it's just an argument - Be a mediator and just solve it without taking sides in the conflict.
You need to know the angle between them.
The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.
A parallelogram has two sets of sides that are parallel to each other (as in, left and right sides are paralell to each other and the top and bottom are parallel to each other), whereas a trapezoid requires two parallel sides (such as left and right) and two non-parallel sides.
The relationship between just the sides is that the sum of any two of them must be greater than the third. Any other relationship involves one (or more) angles.
a trapezoid is made of 4 sides, where two of the sides are parallel and the other 2 are not. a heptagon (if that's what u meant) is a polygon(shape) of 7 sides.
