Triangle, paraellogram(srry if i didnt spell that right...), circle <-- yeah mate it's parallelogram :) an ellipsoid has no right angles. I don't have any right angles either
"Quadrilateral" simply means "four sided". Some quadrilaterals do have right angles; squares or rectangles, for example. Some have one or two right angles, but some don't have any right (90 degree) angles.
Yes a rectangle for example
Some irregular hepagons, for example.Some irregular hepagons, for example.Some irregular hepagons, for example.Some irregular hepagons, for example.
No, all four angles with in a rectangle are right angles.
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees.

Yes a rectangle for example
Some trapezoids For example, the angles of a trapezoid could be: 90, 90, 30, 150

Yes, a trapezoid can have 3 right angles.
No, all four angles with in a rectangle are right angles.
Yes . Some might have acute angles . Most likely right angles .
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees.
Rectangles have 4 rift angles and some parallelogram doesn't have 4 right angles. Only two parallelogram has 4 right angles , square and rectangle
Some do, but not all.
No, some may
Some are larger and some smaller. Also they can be at right angles to each other. See the Related Link below for an example.
