What shapes have at least one pair of perpendicular sides?
Any shape, other than a triangle can have a pair of perpendicular sides.
What shapes has no pair of perpendicular sides?
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
What type of triangle has one pair of perpendicular sides?
A`isoseles duhhh
Does a triangle only have one pair of parrell sides?
A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
How many pairs of perpendicular sides does a right triangle have?
Perpendicular means meeting at a right angle. A right triangle has 2 sides that are perpendicular, so it has 1 pair of sides that are perpendicular They are known as the "legs" of the right triangle.
Which shape has no parallel sides but at least 1 pair of adjacent perpendicular sides?
It could be a right angle triangle
What shape has one pair of adjacent perpendicular sides but no parallel sides?
It fits the description of a right angle triangle
What shape has exactly one pair of perpendicular sides?
I am sure there are several; the simplest would be a right triangle, which means, a triangle with a right angle.
Does a dodecagon has no pair of perpendicular sides but has pair of perpendicular sides?
The question contradicts itself. A dodecagon need not have any perpendicular sides.
Which shape has no pair of perpendicular sides but no parallel sides?
shape no pairs of perpendicular sides
If orthocentre and circumcentre of a triangle coincide then is it an equilateral triangle?
Yes. The orthocenter is the intersection of the altitudes; the circumcenter is the intersection of the perpendicular bisectors of the three sides of the triangle. The perpendicular bisector of and altitude to a given side are parallel, so they can coincide at the common center only if they are the same; that means that the opposite vertex is on the perpendicular bisector, so the other two sides are equal. Thus each pair of sides are equal, so the triangle is equilateral.
Can a triangle have a pair of parellel and perpendicular lines?
No parallel lines but a right angle triangle has perpendicular lines.
