yes. A square has four sides and all four angles are 90 degrees, so it is a rectangle. However a rectangle's sides are not always all the same length so a rectangle is not necessarily a square.
A right triangle has three sides, one of its angles is 90 degrees and the other two add up to 90 making it have 180degrees total. Every triangle's angles add up to 180 degrees but not all have a right angle. so although a right triangle is a triangle, a triangle isn't necessarily a right triangle.

Basically, a square is defined as having four sides equal in length and four 90 degree angles. A rectangle also has four sides and 90 degree angles, but does not have sides equal in length. So, a square can be definied the same as a rectangle: that it has four sides and four 90 degree angles. But a rectangle can't be definited as a square, having four equal sides, because it doesn't. Make sense?

That's not quite correct. SOME rectangles are squares.
---------------
Here's a true statement:
"If it is a square, then it is a rectangle."
The converse is:
"If it is not a rectangle, then it is not a square."

square is a rectangle because a rectangle is four sided, but a rectangle is not a square because all of the rectangle side is not equivalent. Hm, a rhumbus is a rectangle, but a rectangle is not a rhumbus? idk i'm not that smart.

A parallelogram is a quadrilateral but a quadrilateral is not necessarily a rectangle.
A trapezoid is a quadrilateral, but a quadrilateral is not necessarily a trapezoid.
A kite is a quadrilateral, but a quadrilateral is not necessarily a kite
A rhombus is a quadrilateral, but a quadrilateral is not necessarily a rhombus

All quadrilaterals are polygons but not all polygons are quadrilaterals, it is not a biconditioanl statement.
