Chapter 6 Review

6-1 through 6-5

Fill in the Blanks

Q1: What is the measure of each interior angle of a regular 20-gon?

Type answer...

Interior Angle Sum Theorem:

s=180\left(n-2\right)

$s=3240\degree$
divide by n.
Each angle = $162\degree$

Fill in the Blanks

Q2: If the interior angle of a regular polygon measures

108\degree

, how many sides does the polygon have?

Type answer...

Exterior Angle Sum Theorem

Linear Pair Theorem: Exterior Angles = $72\degree$
$\frac{360}{72}=\ 5\ sides$

Multiple Choice

Q3: What is the name of this polygon?

Pentagon

Hexagon

Heptagon

Octagon

Fill in the Blanks

Q4: The figure is a regular polygon, find the value of x.

Type answer...

Interior Angle Sum =

540\degree

Divide by the number of sides
$9x-18=108$
OR...
$5\left(9x-18\right)=540$
x = 14

Fill in the Blanks

Q5: If $m\angle ABC=115\degree$ , find $m\angle ADB$ .

Type answer...

$m\angle ABC=115\degree$ , find $m\angle ADB$

Alternate Interior Angles + Angle Addition: $6x-11+4x+6=115$
x = 12
$m\angle ADB=61\degree$

Multiple Choice

Q6: Is there enough information to determine that this quadrilateral is a parallelogram?

yes, opposite sides are congruent

yes, opposite sides are parallel

no, not all pairs of opposite sides are congruent

no, not all pairs of opposite sides are parallel

Multiple Choice

Q7: State which method we can use to show that the quadrilateral is a parallelogram.

Both pairs of opposite angles are congruent.

Both pairs of opposite sides are congruent.

Both pairs of diagonals bisect each other.

Both pairs of opposite sides are parallel.

Fill in the Blanks

Q8: Find $m\angle XZW$ .

Type answer...

Def. Rectangle + Acute Angles Complementary

$5x-8+x+20=90$
x = 13
Def. Complementary: $m\angle XZW=57\degree$

Fill in the Blanks

Q9: If $m\angle XYZ=136\degree$ , solve for x.

Type answer...

$m\angle XYZ=136\degree$

Consecutive Angles Supplementary:
$m\angle YZW=44\degree$
Angle Bisecting Diagonals:
$10x-8=22$
x = 3
