An angle is formed by two rays sharing a common end point, called a vertex. However, an angle can also be a measurement of rotation. The word angle is Latin based and means "corner."Answer and Explanation: There are several ways you can make a hexagon. The standard hexagon has all ...
As the exterior angles are created by the extended straight line, an exterior angle and its corresponding interior angle must always add together to make 180°. Exterior angles of a hexagon My own image Calculating the Sum of the Exterior Angles To calculate the sum of the exterior angles, im...
How many degrees do the exterior angles of a triangle sum up to? How many triangles make a hexagon? What degree of rotational symmetry does an equilateral triangle have? How many degrees in a right triangle? How many unique triangles can be made where one angle measures 60 degrees and anoth...
A pentagram is the shape of a five-pointed star polygon. It is also known as a star pentagon due to its shape and thepentagonin its center, which explains the origin of the word pentagram. In the past, the pentagram symbol has also been used as a holy sign to represent goodness, and...
What is the measure of 1 interior angle of a regular octagon? Show Answer Substitute 8 (an octagon has 8 sides) into the formula to find a single interior angle Problem 6 Calculate the measure of 1 interior angle of a regular dodecagon (12 sided polygon)? Show Answer Substitute 12 (...
Octagon 1080° 135° Nonagon 1260° 140° Decagon 1440° 144° Dodecagon 1800° 150° What Is a Polygon? A polygon is a 2-dimensional shape with straight sides. Why Does the Formula Work? The interior angles of a three-sided shape (a triangle) add up to 180°. To make a four-side...
Supplementary Angles - Two angles such as ∠α and ∠β in figure 2, whose measures add up to 180°, or that make a straight angle (straight line), are said to be supplementary. In figure 2, the angles were adjacent to each other, but they dont have to be adjacent to be classified...
Explain how to find the sum of the measures of the exterior angles of a polygon. 1. Find the measure of each interior angle of a regular octagon. 2. Find the sum of the interior angle measures of a convex pentagon. Find the number of diagonals, the measure of an interior...
