Area of a stop sign if the measure of a side is 10 inches?
a stop sign has eight sides. ten times eight is eighty, therefore the awenser is eighty inches
What is the perimeter of a stop sign if one side measures 12 inches?
Perimeter is total edge length. A stop sign has 8 sides, so 8"*12=96"■
Where can you find a octagon?
As a stop sign
What does a regular hexagon look like?
It looks like the shape of a STOP sign except that it has only six sides.
Is there a relationship between a polygon's number of sides and its number of vertices and angles?
For a regular polygon, all sides are equal and all angles are equal. Draw a regular hexagon. This website shows you an easy way to draw a hexagon with a compass. http://www.wikihow.com/Draw-a-HexagonDraw a line from one vertex to another going thru the center. This should make 2 identical triangles. Do this, until you have 6 triangles. Use a protractor to measure the 6 angles in the center and the base angles. They should each be 60º angles. Two of these adjacent base angles measure 120º. This is the vertex angle. There are 6 vertices, 6 sides, 6 - 60º angles in the center, and 6 - 120º angles at the 6 vertices.1. If a polygon has n sides, there will be n angles at the center, n vertices and n triangles.2. Draw the 5 lines connecting each vertex to the center of the polygon making 5 angles.There are 360º around the center point, so 360º ÷ n is the measure of each angle at the center.The angle of the triangle at the center of the polygon = 360 º ÷ n. This angle is the angle of the triangle at the center of the polygon.The sum of the interior angles in a triangle = 180ºThe sum of the 2 base angles of each triangle must be 180 º - (360 º÷ n).Each of the base angles of the triangle must measure (180º - (360 º÷ n)) ÷ 2.Two adjacent base triangles from adjacent triangles form a vertex angle, so the vertex angle = 2* (180º - (360 º÷ n)) ÷ 2.Two adjacent base angles = one vertex angle.The vertex angle = 2 * (180º - (360 º÷ n) ÷ 2, which means you do not have to divide by 2. You can stop at step #6.Now let's try a sample problem. Here is a site for constructing a pentagon. http://www.kjmaclean.com/Geometry/PentConstruct.htmlFind the relationship between a pentagon's number of sides and its number of vertices and angles? Since a penta means 5, a pentagon has 5 sides, 5 vertices, and 5 angles. Now let's find the vertex angle.Since a penta means 5, a pentagon has 5 sides, 5 vertices, and 5 angles.5 angles360º ÷ 5 = 72ºThe angle of the triangle at the center of the polygon = 72º72 º + nº + nº = 180º180 º - (360 º÷ 5) = 108ºEach of the base angles of the triangle must measure 108º ÷ 2 = 54 ºThe vertex angle = 2* 54 º = 108ºNotice that the answer to #6 and #8 are the same.
What is the sum of the interior angle of a stop sign?
1,080°
What traffic sign is an obtuse angle?
American "STOP" sign (135° inner angle).
Real life example of a straight angle?
The angle between the part of the street before the STOP sign and the part of the street after the STOP sign is usually a straight angle.
What is the angles of a stop sign?
The angles are obtuse angles. The stop sign is octagonal in shape. Assuming it is a regular octagon, then: exterior_angles = 360o ÷ 8 = 45o -> interior angle = 180o - 45o = 135o
What are the angle measures to a stop sign?
formula for interior angles of a regular convex polygon is 180 * (n-2)/n A stop sign is an octagon, and has 8 sides 180 * (8-2)/8 180 * 6/8 180 * 3 / 4 145 ■
Does a stop sign have a least one right angle?
Yes
What are the degrees of the interior angles of a stop sign?
360 / 8 = 45
Area of a stop sign if the measure of a side is 10 inches?
a stop sign has eight sides. ten times eight is eighty, therefore the awenser is eighty inches
Are all the sides of a stop sign the same measure?
A stop sign is normally a reguar polygon of some sort, such as a regular octagon, so all sides have the same length.
What is the interior angles of a stop sign?
3x squared - 12x - 24 = 0, and -b/a = sum of the roots, and c/a = product of the roots
What unit of measure would you use to measure the area of stop sign?
Square feet. ************************* I would use centimetres to give the area in square centimetres.
What is 8 s on a s s?
8 Sides on a Stop Signsides on a stop sign
