Point, Endpoints, and Angles
Any specific location in space can be indicated by a point.
The shortest distance between two points (i.e arbitrary Point A and Point B) is a straight line. In this line, Points A and B are called endpoints, and the line between these endpoints is called a line segment. Therefore, endpoin... | 677.169 | 1 |
Make and test a conjecture about the number of diagonals of a pentagon. Write a conjecture for the general case.
The correct answer is: 6(6 - 3)/2 = 9
We will consider a pentagon
We observe that there are 5 diagonals in a pentagon. Now, for an "n" sided-polygon, the number of diagonals can be obtained by the followi... | 677.169 | 1 |
