A scalene triangle has all sides of different lengths.
An octagon is a polygon with eight sides.
A chord is any line segment whose endpoints lie on a circle.
An obtuse triangle has one angle greater than 90 degrees.
The perimeter of a square is 4 times the side length, thus 4 x 5 = 20 units.
The distance around the edge of a circle is called the circumference.
