Does the triangle has parallel side and perpendicular side?
No triangle can have parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees
Does a rght triangle need parallel and perpendicular lines?
Perpendicular lines meet at a right angle so a right angled triangle has two lines which are perpendicular to eachother. However there are no parallel lines in a right angled triangle, or any triangles for that matter.
What shape has perpendicular sides but no parallel lines?
A right angle triangle.
What shape has no parallel lines and no perpendicular lines?
A regular pentagon does not have parallel or perpendicular lines. Some other possibilities include, but are not limited to:a circlean ovalan equilateral triangle or any triangle that is not a right triangle.(A right angle's lines are perpendicular. Those are what make it a 90 degree angle.)
What are perpendicular and parallel lines on a polygon?
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).

Does a triangle have parallel and perpendicular sides?
A triangle has no parallel sides but in the form of a right angle triangle it has perpendicular lines that meet at right angles which is 90 degrees.
Can a triangle have a pair of parellel and perpendicular lines?
No parallel lines but a right angle triangle has perpendicular lines.
What is perpendicular adjacent sides in the triangle?
The perpendicular adjacent sides in the triangle would be 3 sides. It is the basically horizonstal line next to a vertical line(perpendicular) if it was parallel adjacent then only two side of triangle /\ <-- parallel
How many parallel and perpendicular lines are they in a right angle triangle?
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.

What is a trapezoid with one side perpendicular to the parallel sides?
right triangle

Prove that the tangent at a to the circumcircle of triangle abc is parallel to bc where triangle abc is a isosceles triangle?
The circumcircle of a triangle is the circle that passes through the three vertices. Its center is at the circumcenter, which is the point O, at which the perpendicular bisectors of the sides of the triangle are concurrent. Since our triangle ABC is an isosceles triangle, the perpendicular line to the base BC of the triangle passes through the vertex A, so that OA (the part of the bisector perpendicular line to BC) is a radius of the circle O. Since the tangent line at A is perpendicular to the radius OA, and the extension of OA is perpendicular to BC, then the given tangent line must be parallel to BC (because two or more lines are parallel if they are perpendicular to the same line).
What are perpendicular and parallel lines on a polygon?
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).
Does an equilateral have parallel or perpendicula?
We'd need to know the number of sides. An equilateral triangle won't have any parallel or perpendicular sides. An equilateral quadrilateral will have two pairs of parallel sides which may or may not be perpendicular.
