Are some trapezoids rectangles?
Oh, dude, like technically speaking, all rectangles are trapezoids, but not all trapezoids are rectangles. It's like saying all squares are rectangles, but not all rectangles are squares. So, yeah, some trapezoids can be rectangles, but not all of them. It's like a geometry mind game, man.
Is it true or false that some trapezoids are squares?
false
Is a quadrilateral a trapezoid?
No, a quadrilateral isn't always a trapezoid. One way to consider it is that all trapezoids are quadrilaterals (four-sided shapes), but not all quadrilaterals are trapezoids. Some quadrilaterals are concave quadrilaterals, some are scalene convex quadrilaterals (called trapezoids in the UK), some would be trapezoids, and some would be parallelograms (rectangles, squares, rhomboids, rhombi). If parallelograms are considered a special case of trapezoids, then trapezoids would include all non-scalene convex quadrilaterals, which is a highly inclusive definition.
How do you mean all quadrilaterals are trapezoids?
We don't know who said that, but it's not true. Some quadrilaterals are trapezoidsand some aren't.A quadrilateral is any drawing with four sides.A trapezoid is any drawing with four sides and two of the sides are parallel.So all trapezoids are quadrilaterals. But there are a lot of other quadrilateralsthat aren't trapezoids.
True or false A theorem is a statement that is deductively proven to be true.?
False. It is proven to be true IF some axioms are assumed to be true. A mathematical statement can be proven to be true only after some axioms have been assumed.

false
Do some parallelograms have equal diagonals true or false?
True when they are in the form of rectangles.
There are some parallelograms which are not rectangles true or false?
yes. rectangles are just the special cases of parallelograms where the angles are all 900
What 4 sided shapes have right angles in them?
Squares, rectangles, and some trapezoids.
Are some rectangles also trapezoids?
True. All rectangles are trapezoids. (In England a trapezoid is known as a trapezium.)
Some rectangles are not parallelograms?
false
There are some properties of quadrilaterals which are not properties of rectangles?
false

There are some parallelograms that are rectangles?
True
Is it true that some quadrilaterals are neither trapezoids nor parallelogram?
Yes.
