For this next unit, we are going to go over circles, and this first section of the unit is parts of the circle. First we'll go over the different segments in a circle. You'll get familiar with the terms like circle, chord, diameter, radius, secant, and tangent. A circle is usually called by its center. This means that if a center of a circle is a point P, then the circle is going to be called circle P. You'll learn what a diameter of a circle is, and also how diameter and radius are connected. You'll also learn the differences and similarities between secants and chords.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
