What polygon has 2 right angles and 1 set of parallel lines?
Answera polygon that has two right angles and one set of parallel lines is a hexagon
How many parallelograms are formed when a set of 5 parallel lines intersect a set of 4 parallel lines?
This one is much more straightforward. There are 5C2 = 10 ways to choose two parallel lines from the set of five. There are 4C2 = 6 ways to choose two parallelograms from a set of four. Any parallelogram is uniquely determined by one pair of lines from the five, and one pair of lines from the four. Thus, the number of possible parallelograms is(5C2)*(4C2) = (10)*(6) = 60
What is the name of a set of parallel lines?
There isn't a name...they're just called a pair of parallel lines.
Do graph of a system of parallel lines will have no solutions?
Correct. Unless the parallel lines are coincident, in which case the solution set is the whole line.
Does parallel lines always have the same slope?
Yes, that's what makes them parallel lines - they have the same slope. So they never will intersect with each other. If a set of lines didn't have the same slope, at some point they would intersect and thus would not be parallel.
What polygon has 2 right angles and 1 set of parallel lines?
Answera polygon that has two right angles and one set of parallel lines is a hexagon
What polygon has 1 set of parallel lines?
trapezoid
Any polygon with two right angles and one set of parallel lines?
That would be a right trapezoid.
Four sided polygon with one set of parallel lines?
Rhombus, actually all the lines are parallel even though it is an offset square. what you want is a trapezoid or some variation there of.
What shapes have one set of parallel lines?
A parallelogram always has one set of parallel lines, plus another set also.A trapezoid (trapezium) always has exactly one set of parallel lines and no more.Any shape with more than four sides can have one set of parallel lines, but doesn'tnecessarily have to.
What is a figure that only has one set of parallel lines no perpendicular lines and at least one acute angle and the one obtuse angle?
A polygon with four or more sides can meet all of the requirements.
Who many lines of parallel does a trapizoed have?
A trapezoid has one set of parallel lines.
Does a triangle have a set of parallel lines?
No. it is the only polygon that can not have parallel lines all though any regular polygon with an odd number of lines will have no parallel lines If three points were in a straight line it could be argued that these formed a triangle with parallel sides, though really it would be just a line; or if we had a triangle with infinite height the sides would be parallel. In any other case, no.
What polygon has 4 sides 2 right angles and 1 set of parallel lines?
It would be a rectangle.
What polygon has only one set of parallel sides?
A trapezoid.
Does a trapezoid have to have one set of parallel lines?
Yes. The top and bottom lines of a trapezoid are parallel.
What is a quadrangle with one right side?
a trapezoid would work as long as there is still one set of parallel lines and one set of non-parallel lines.
