Do all rectangles have adjacent sides that are perpendicular?
Yes, otherwise it would be a different shape such as a rhombus or trapezium.
Does a square have adjacent sides that are perpendicular?
yes, in a sq. or a rec. , all adjacent sides are perpendicular
What quadrilaterals have all adjacent sides perpendicular?
Rectangles. (Which includes squares.)
What four sided figure that all adjacent sides are perpendicular?
A square.
Are the adjacent sides on a parallelogram perpendicular?
Generally no. If they are perpendicular, all four angles are right angles and the parallelogram is usually called a rectangle.
What shape has 4 side all congruent none are perpendicular?
It is a rhombus
Are all sides perpendicular in a rectangle?
Adjacent sides are perpendicular. Opposite sides are parallel.
Name the perpendicular adjacent sides in the triangle?
all the sides
What quadrilaterals have all adjacent sides are perpendicular?
Square & Rectangle are the only two. Rhombus (diamond) & parallelogram have adjacent sides, but no 90 degree angles (not perpendicular).
How many perpendicular faces does a rectangular prism?
All of the adjacent faces are perpendicular. So there are 6 faces x 4 faces adjacent to each face So there are 24 perpendicular faces in a rectangular prism.
What is a perpendicular shape?
A perpendicular shape is one where either one or more or even all of the angles are right angles. Some examples are rectangles and squares.
What shape has no right angles adjacent sides the same length?
an equilateral triangle (all sides are adjacent and 60 degrees)
Is a consecutive sides of a square are perpendicular to each other?
Yes. Squares only contain 90 degree angles, so all sides are perpendicular to the adjacent sides and parallel to the opposite one.
Do all squares have two parallel sides?
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
Does a rhombus have a perpendicular side?
A wonderful and rare property of a rhombus is that its diagonals are always perpendicular to each other.
Why cosine 0 degree equals 1?
The cosine of an angle is equal to the length of the "adjacent" side divided by the length of the "hypotenuse" of a right triangle formed by a horizontal line (called the "adjacent side"), another line (the "hypotenuse") intersecting the first line at the specified angle, and a third line (called the "opposite" side) drawn perpendicular to the first line and intersecting the second line. Note that it does not matter how far away from the angle you draw this third line, because the trigonometric functions are all ratios, and they hold true not matter how large or small the actual lengths.Now, if the angle in question is zero degrees, then there is no difference between the first two lines (adjacent and hypotenuse). They are the same line. The distance between them, at all points, is zero. If you try to draw the third line, it will not be a line at all, but just a point, which lies on both the adjacent side and the hypotenuse. And at this point, the lengths of the adjacent side and the hypotenuse will be identical. Remember that the cosine is defined as the length of the adjacent side divided by the length of the hypotenuse. But these lengths are the same, so you're dividing a number by itself. And when you do that, the answer is always 1.
What makes a rectangle a special parallelogram?
A rectangle is a special form of parallelogram that has adjacent sides perpendicular to each other or all the inside angles are 90 degrees.
