in ACTIVITY 3: Fill in the blank/s with word/s that will best complete the statement. is a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center). OO2. A of a circle is the region bounded by an arc and the segment joining its endpoint while of a circle is the region bounded by an arc of the circle and the two radii to the endpoints of the arc. 3. A to a circle is a line coplanar with the circle and intersects it in one and only one point. 4. A is a line that intersects a circle at exactly two points. 5. An is the part of a secant segment that is outside a circle. Nice one! The activity shows the difference between segment and sector. You are now ready to discover more about sector, segment, tangent, and secant and the knowledge about a circle and its parts, relationship that exists among segments formed by intersecting chords of a circle.X ~ 6.32 Therefore LK ~ 6.32 KC BC What's More At this point, you already know some important ideas about sector, segment, tangent, and secant. Now, using what you have learned earlier about sector, segment, tangent, and secant, answer activity 3 below . ACTIVITY 4: FIND THIS PART! Direction: Given the figure below, solve for the shaded portion or part are using the process given above on solving sector and segment. X 1350 450 12 cm Z 8 cm ACTIVITY 5: Using the theorem on secant segments, tangent segments, and external secant segments, find the length of the unknown (x) segment of the following figures. 1. Let CS = x; LM = 16; and MS = 92. Let BC = 12; AE = 11; and BE = 4. Find the length of BF. D C F What I Have Learned Here is another activity that you may apply what you have learned about tangent and secant, proving theorems on secants, tangents and external secant segments. V 6: WHAT AM
