Answer:

A). True

B). False

C). True

D). True

Step-by-step explanation:

A).Quadrilateral means any polygon with four sides or four edges. Hence a square is a regular quadrilateral with four equal sides or edges.

B). Given any quadrilateral ABCD, BC and CD are adjacent and not BC and AD.

C). A rectangle is an equiangular quadrilateral. Equiangular means having equal angles. Rectangle have all the angles equal of 90 degree. Other example of equiangular quadrilateral is a square.

D). By theorem of parallelogram, if a quadrilateral is a parallelogram, then it has two sets of opposite sides congruent.

Answer:

B. Given quadrilateral ABCD, BC⎯⎯⎯⎯⎯⎯⎯⎯ and AD⎯⎯⎯⎯⎯⎯⎯⎯ are adjacent

Step-by-step explanation:

A. A square has 4 congruent sides and 4 congruent angles, so it is a regular polygon. True.

B. Draw the quadrilateral and label the vertices in the order shown. Given quadrilateral ABCD, BC and AD are opposite sides, not adjacent sides. False.

C. All angles of a rectangle are right angles that measure 90 degrees. True.

Answer:

9.3 inches

Step-by-step explanation:

The computation of the radius of the spinner be given below:

Let us assume the same be x

We know that

Total area of the sector = one-sixth of the total area of the spinner

Given that

45.1 = 1 ÷ 6 × π × r^2

r^2 = 45.1 × 6 ÷ π

r^2 = 86.1

r = 9.279

= 9.3 inches

A farmer wants to use 200 feet of fencing for a chicken pen he wants the width of the pen to be 20 feet what is the length of th

Dominik [7]

The length should be 80 feet.
This is because the width is 20 since there are two sides for the width in pen, we have to add 20+20. This would equal 40. Then we need to subtract 40 from 200. 200-40 would be 160. Then since there are two sides for the length, we need to split that in half. 160÷2 would be 80. To double check, you can do 80+80, and that would still be 160. So the length of one side would be 80. But of course, this whole thing would only be right if the pen has four sides(but since I have seen many chicken pens, there were all rectangular)
