The sum of the exterior angles of ANY polygon is 360 degrees.
You measure angles from either side of the protractor. One set of numbers measures from the left side, the other measures from the right side.
If it has at least one set of parallel sides, then at least one set of angles are congruent
Unit of Measure - Angles are measured in degrees or radians. A degree represents 1/360 of a circle. Each degree is subdivided into 60 minutes. And each minute has 60 seconds. The basic tools used to measure angles are a protractor, compass and set square. Protractor - The protractor is a semi-circular instrument with the degrees marked from 0 to 180. There are two sets of markings; the inner scale goes from right to left and the outer scale from left to right. Compass - A compass is a hinged set of arms. One arm has a pointed end and the other holds a pencil. The compass is used to measure and construct angles. Set Square and Sextant - Set squares are of two kinds--the 90-45-45 degree angle and the 30-60-90 degree angle. They are measuring tools used in drafting and engineering. A sextant is an ancient navigating tool.
It's primarily a template for drawing lines at accurate right-angles and other angles to a line, usually 30º / 60º and 45º for standard set-squares. It's also used for drawing parallel lines. Adjustable set-squares allow you to set off other angles.
It's you dumbo!no its not
360 degrees
The sum of the exterior angles of a polygon add up to 360 degrees.
A convex polygon is one with no reflex angles (angles that measure more than 180 degrees when viewed from inside the polygon). More generally a convex set is on where a straight line between any two points in the set lies completely within the set.
Set up a light source that has narrow beam (a laser pointer is perfect for this).Point it at a mirror,measure the angle of incidence and of reflection.rotate the mirror,measure the angles,continue through many angles,tabulate and graph the results.
In French, 7 is spelled "Sept" which is pronounced just like the word "Set". "Sept" is just one letter away from "Hept", the beginning of "Heptagon". Cheers!
exterior of the angle
You measure angles from either side of the protractor. One set of numbers measures from the left side, the other measures from the right side.
30 60 set squares 45 set square
If it has at least one set of parallel sides, then at least one set of angles are congruent
A set square is a tool for marking angles in engineering and technical drawing, etc. They come in different angles and may be adjustable.
90 degrees
There are no set values for the angles of an isosceles triange. However there will be two angles that are of equal value, and the sum of the angles will add to 180 degrees.
