A quadrilateral in which adjacent angles are congruent?
If all adjacent angles are congruent, it can only be a rectangle (or square).
How many pairs of equal angles has a parallelogram?
There will be two pairs. It is possible for all four angles to be identical.
Are all pairs of vertical angles equal?
yes
How many pairs dose a square have?
It has 6 possible pairs of sides, although all the pairs will look the same. It has 6 possible pairs of angles, although all the pairs will look the same.
What are five characteristics of a rectangle?
* both pairs of opposite sides are parallel * both pairs of opposite sides are congruent * all angles are 90 degrees * both pairs of opposite angles are congruent * the diagonals bisect each other.
Why do all linear angle pairs must be supplementary but all supplementary angles do not have to be linear pairs?
All supplementary angles would be linear pairs IF they were adjacent. But they could be far apart.
What shape has 2 pairs of congruent sides with those sides being non-adjacent and the angles are not all congruent?
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
Are all pairs of supplementary angles adjacent?
whenever you have a supplementary angle, you know that both of the angles in the supplementary angles will add up to 180 degrees. if that's what you meant
A garden has 2 pairs of congruent sides the congruent sides are not adjacent and the angles are not all congruent what is the shape of the garden?
obtuse
What is the name of a quadrilateral which has two pairs of adjacant sides and its diagonals interscect at 90?
All quadrilaterals have two pairs of adjacent (ie next to one another) sides. Diagonals intersect at right angles suggest a kite (or square).
Which quadrilaterals always have diagonally adjacent angles?
All quadrilaterals have diagonally adjacent angles.
What quadrilateral have adjacent sides not equal two pairs of congruent sides and the little right angles?
A rectangle is the only such shape. Not sure about the "little" right angles: all right angles are of the same measure.
What is the name of the special quadrilateral that has the angles of 80 100 80 and 100?
A rhombus is a parallelogram with all its sides equal in length but none of its internal angles are right angles. If both pairs of opposite sides are of equal but different lengths then the quadrilateral is a simple parallelogram.If the two pairs of adjacent sides are of equal but different lengths then the shape is called a kite.
Which pairs of angles are formed by two intercepting line?
A pair of opposite angles. The sum of all four angles is 360 degrees. Any two adjacent angles are supplementary to each other and add up to 180 degrees
A quadrilateral in which adjacent angles are congruent?
If all adjacent angles are congruent, it can only be a rectangle (or square).
In a rectangle all 4 sides must be?
Straight. That is the only requirement which applies to all four sides. In pairs, the sides have to be equal and parallel but that does not apply to all four. In [adjacent] pairs, the sides have to be at right angles, but that does not apply to all 4.
What are angles that are formed when two lines intersect?
When two unique lines intersect, two pairs of equal angles will be formed. All four angles could be 90 degrees (right angles) if the lines are perpendicular. If the lines are oblique, the pairs of angles can vary (almost) infinitely within a given range (1 degree-179 degrees).The intersection of two lines results in two pairs of equal angles such that the sum of angles equals 360. Another way to state this is that two adjacent angles will always sum to 180 degrees. That said, the best we can do is to express one angle in terms of the other. Call a pair of adjacent angles a and b. In the case of two adjacent angles, a = 180 - b, or b = 180 - a.
