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!

A set square is a tool for marking angles in engineering and technical drawing, etc. They come in different angles and may be adjustable.

If it has at least one set of parallel sides, then at least one set of angles are congruent

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.

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.

Each inside angle measures 55 degrees. Outside angles measure 135. If you were making an octagon out of wood or other material, you would set your miter saw to 55 degrees for a flush attachment.

A trapezoid is a quadrilateral with a set of parallel lines. Because it is a quadrilateral, it has four angles.

Rectangles have 2 pairs of right angles.

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.

There are two shapes to cover the two most common sets of angles used in mathematical constructions. The first set square contains 45o-45o-90o angles The second set square contains 30o-60o-90o angles

No it's just a prop for the show, the exterior and interior are two separate things, the exterior is just a shell with nothing inside and the interior is a set on a stage.
