What is the name of the line segments that make up a triangle?
The line segments that make up any polygon are called its sides.
Calculate the number of sides of a regular polygon whose interior angles are each 156 degrees?
Exterior angle = 180-156 = 24 degrees Number of sides = 360/24 = 15 sides. If you can't remember the formula, then remember this to help figure it out: The regular polygon can be divided into triangles (like pizza slices). Each triangle is an isosceles triangle and all of them are congruent (since it's a regular polygon). Take one of the triangles: each of the 'leg angles' will be half of the polygon angle (the leg of the triangle has bisected the polygon angle). So these two angles will add together to be the same measure as the polygon angle (call it Ap). So the other angle in the triangle is in the center and all these pizza slice angle make a circle in the middle (360°). Since the triangle sums to 180°, the angle in the middle is (180° - Ap), then you have: Number of sides = (360°) / (180° - Ap), or in this case: 360/(180-156) = 15 sides.
What does polygon mean in math?
A polygon is a shape made of three or more straight lines that surround a closed space. If you had three lines that did not make a triangle but instead looked like the letter "N," that would not be a polygon because the lines don't close a space. A space is closed when it is entirely surrounded by lines.Hope that helped :D
If you fold a polygon half twice to make a rectangle what would the polygon look like?
the polygon would be a square
What polygon that has at least one right angle?
A right triangle or a rectangle are polygons that have at least one right angle. There are other quadrilaterals and many irregular polygons that could have at lease one right angle, too. Many of them. Note that a polygon is any planar figure constructed of a finite number of line segments to make a closed figure. By that definition, which is a correct one, the triangle and rectangle are polygons. And a quadrilateral (of which the rectangle is special case) can be constructed with just one right angle, though it will be a bit quirky looking. Once we start adding sides to make different polygons, the game is afoot because so many possibilities exist.
