Hey there! I'm happy to help!
A <u>quadrilateral </u>is any polygon (enclosed shape) with four sides. Let's see what each of these shapes are.
- Scalene right triangle - the prefix <u>tri-</u><u> </u>means <u>three </u>(tricycle, tripod, triple, etc.<u>),</u> and all triangles have three sides, so this is not a quadrilateral.
- Obtuse scalene triangle - once again a triangle, so not a quadrilateral.
- Isosceles right triangle - would you look at that, another triangle! Not a quadrilateral.
- Hexagon - a hexagon is a six-sided polygon (<u>hex=six)</u>, so this is not a quadrilateral.
- Pentagon - a pentagon is a five-sided polygon (<u>pent=five, </u>like Pentatonix!). Not a quadrilateral
- Right trapezoid - a trapezoid is a quadrilateral with at least one pair of parallel sides!
- Venn diagram - a Venn diagram is a compare and contrast chart made of two overlapping circles (ZERO sides), so this is not a quadrilateral.
So, the only shape on your list that is a quadrilateral is 6. right trapezoid.
Have a wonderful day! :D
Answer:
Yes
Step-by-step explanation:
Hi there,
Yes, the definition of a rectangle is "a plane figure with four straight sides and four right angles." A square has all of these, so by definition, a square is a rectangle.
But be careful! A square IS a rectangle but a rectangle IS NOT a square!
Hope this helps! Stay safe!

Answer:
d <u>></u> 9
Step-by-step explanation:
An easy way to do these questions is to treat the >/</<u>></u>/<u><</u> symbols as if they were an equals sign.
So for this question, pretend it is d+13=22 then take away 13 from both sides which will give you d=9, then after that you'll just switch the symbol back and write your answer as d <u>></u> 9.
Hope this helps :)
