Which shapes are quadrilaterals?

lubasha [3.4K]

Hey there! I'm happy to help!

A quadrilateral is any polygon (enclosed shape) with four sides. Let's see what each of these shapes are.

Scalene right triangle - the prefix tri- means three (tricycle, tripod, triple, etc.), 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 (hex=six), so this is not a quadrilateral.
Pentagon - a pentagon is a five-sided polygon (pent=five, 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:

4√3

Step-by-step explanation:

5√27-2√48-5√3-(√3-2√3)2

= 5√(3x9)-2√(3x16)-5√3-2√3+4√3

= 5(3)√3-2(4)√3-5√3-2√3+4√3

= 15√3-8√3-5√3-2√3+4√3

= 4√3
