7 because 3(3+1)/2)+1 eqauls 7.
3(4)/2)= 6 and so if you add 1 you get 7

What is the maximum number of parts a circle can be divided by using four straight lines?
11
How do you find the sum of the measure of interior angles?
(number of sides - 2)*180 = total sum of interior angles
Is there a formula for finding the measure of interior angle of a regular polygon?
Yes and it is: sum of interior angles/number of sides
What is the size of an interior angle on a regular 15-sided shape?
156 degrees Sum of interior angles of a polygon=180(n-2), where n is the number of sides. To find one interior angle's measure, divide by the total number of angles, which is also the total number of sides.
Is there a minimum number of acute interior angles that any polygon can have?
Although a triangle must have at least two acute interior angles, a square has four interior right angles and no acute angles. And as regular polygons have increasing numbers of sides, their interior angles get larger.
What is the maximum number of separate interior regions that can be formed by the intersection of two equal cubes?
17 - each of the 8 point out corners on the two cubes and the middle section
What is the maximum number of regions you can make in a plane using six lines?
22
What is the maximum number of regions that can b formed by five congruent circles?
21
What is the maximum number of sides a polygon can have if each interior angle is obtuse?
Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.
What is the most number of regions you could divide a plane into with 4 straight lines?
11
What polygon's interior angles add up to the same number of degrees as a straight angle?
A straight angle has 180 degrees. A triangle is a polygon whose interior angles add up to 180 degrees.
Which is the polygon with the maximum number of sides?
a circle * * * * * No. A circle is not a polygon because a polygon MUST have straight sides. There is, however, no maximum number - just like infinity being the biggest number.
What is the smallest number of straight lines needed to divide the plane into exactly 5 regions?
3
What are regions on a geoboard?
Well...regions on a geoboard is basically just a geoboard split into a certain amount of sections. Say you had a geoboard with a band stretched diagonally across with one segment (line) it would be 2 regions. If you had 3 segments (lines) the maximum number of regions would be seven. Geoboards are really fun but i personally like regions the best. A challenge is to find all the maximum number of regions from 1-9..its actually really hard and no number 4 is snot 10 it is 11!! Good Luck!

What does 2080 work hours equal?
The maximum number of "straight time" work hours in a calendar year.
How does the number of sides relate to the number of interior triangles?
The number of sides and the number of interior angles are the same.
