How many angles does a regular polygon have when its interior angle is 176 degrees

Lots and lots and lots. When you think the angle is nearly 180 degrees or a straight line, it must have lots and lots of sides.

The total of the interior angles of a polygon is given by (n-2)180, so the angle of each interior angle of a regular polygon is given by ((n-2)180)/n.

Now we set this to be equal to 176 and solve for n.
(n-2)180 = 176
-----------
n

Multiplying both sides by n, we get (n-2) 180 = 176n

Expanding the left side of the equation, 180n - 360 = 176n

Subtracting 176n from both sides and adding 360 to both sides, we get

180n - 176n = 360

4n = 360

Dividing both sides by 4, n = 90

Thus, you need a regular polygon of 90 sides to get an internal angle of 176 degrees.

Hopefully you don't have to construct it.

Good luck,

What is the number of diagonals of a regular polygon whose interior angle measures 144 degrees?

180(n-2)=n*144 in our case
solving for n we obtain:
36n = 360
n=10 sides

If the ratio of the corresponding side lengths of two similar polygons is 5:9, what is the ratio of their perimeters?

This works for any polygon:

Say you have 2 squares - the sides are 5 and 9
Perimeter 1 = 20
Perimeter 2 = 36

20:36 = 5:9

What follows is true for CONVEX polygons.
Let n be the number of sides of a convex polygon, and let n be greater than or equal to 4, then
The number of diagonals is given by n*(n-3)/2
Using this rule, write n*(n-3)/2=20. Clear the fraction, open brackets. You end up with n^2-3n-40=0.
Factor the polynomial or use the formulas for the quadratic equation to find the roots as n=-5 or n=8. Discard the negative root because n must be positive.

How do convex polygons differ from non-convex polygons?

A convex polygon is one with each of its interior angles less than 180 degrees and every line segment between any of its two vertices remains inside or on the boundary of the polygon.

Example of a convex polygon (WIKIPEDIA)

A concave polygon will always possess an interior angle with a measure that is greater than 180 degrees.
