An arc of a circle is any part of it's circumference. Arcs are used when describing sectors and segments of circles.
A chord is a straight line that separates a circle into two parts. A chord defines two arcs on the circumference of a circle at the two points where it touches the circumference.
A sector of a circle is the area enclosed by two radii connected by an arc on the perimeter. When you think of pie charts, each wedge shaped area is a sector of the circle.
A segment of a circle is an area encolosed by an arc and a chord. If you imagine the circle as a round cheese, a segment is what you would get if you sliced through the cheese from edge to edge with a cheese wire (as long as the cheese was two-dimensional..).
A tangent is a straight line outside a circle that touches the circle at one point only. The point where the tangent touches the circle is called the point of tangency. The radius of the circle from the point of tangency is always at right angles to the tangent.
With our Four in a row math game you will be practicing the topic "Parts of the circle 2" from 8th grade / Geometry & measures / Circle / Circle. The math in this game consists of 16 questions that ask you to identify parts of the circle: arc, chord, sector, segment and tangent.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
