A square, a rhombus and a kite
Two straight lines that meet at right angles are perpendicular.
An irregular pentagon is a polygon that has five sides and two right angles. A regular polygon on the other hand does not have right angles.
The contrapositive to the statement, "if two lines intersect to form right angles, then they are perpendicular," is "if two lines are not perpendicular, then they do not form right angles."
If two lines intersect at right angles then they are perpendicular!

They are equal.
Two lines are perpendicular if they cross at 90 degree angles.
yes it is A trapizium has no right angles therefore there are no perpendicular.* * * * *Nonsense! A trapezium can have two adjacent angles which are right angles.
Any polygon can have two interior angles of 12 degrees. No polygon can have all its interior angles of 12 degrees.
its impossible; the two perpendicular lines already make four right angles.
