Parallel sides do not intersect. Perpendicular sides intersect at a right angle.
no, they have congruent angles
Squares and rectangles
A square or a rectangle
they intersect 1 point at a 90 degree angle at all sides
A single side cannot be perpendicular on its own. Two sides are perpendicular if they intersect at a 90 degree angle. There are many polygons, both regular and irregular, that can have perpendicular sides.
Parallel sides do not intersect. Perpendicular sides intersect at a right angle.
That's impossible because a polygons lines cannot intersect
no, they have congruent angles
Squares and rectangles
A square or a rectangle
A square, a rhombus and a kite all have perpendicular diagonals that intersect at right angles
they intersect 1 point at a 90 degree angle at all sides
The perpendicular bisectors of the sides of a triangle intersect at its circumcentre.
The three ANGLE bisectors of a triangle also bisect the sides, and intersect at a point INSIDE the triangle. The angle bisectors are not necessarily perpendicular to them. The perpendicular bisectors of the sides can intersect in a point either inside or outside the triangle, depending on the shape of the triangle.
No.
A rectangle, and selected irregular polygons of 5 or more sides. Also, all regular polygons on 4n sides where n is an integer.
