ACTIVITY 6 "CIRCLE"
Description of Activity:
The student will understand that is a circle. Mentioned and chart their lines and significant segments using GeoGebra. Carry out examples to help understand this concept and relates to everyday life.
Development Activity:
1. Mentioned the concepts of circumference and circle. Are they different? Explain.
2. In the next figure mentioned the name of each segment or line and write its definition.
3. Describe examples of everyday life that represent a circle and straight segments and notable figure involved in (at least 5 examples and preferably not tapas). You can take photos for your example and append them to work.
4. Draw a circle in GeoGebra using the circle tool given its center and radius of which is 17.5 cm diameter. Draw two chords that do not pass through the center. Trace the bisectors and checks that pass through the center of the circle. Do not delete your auxiliary lines marks only give them a different color.
5. Describe the method to draw a tangent line passing through a point that belongs to the circle and then take it out on the lines marking GeoGebra be addressed.
6. Now with the procedure seen in the face session in GeoGebra draw a circle with the circle tool given its center and radius, now select a point that is outside of the circle and then draw the tangent line. Describe your procedure by checking each line of a different color for the procedure performed.
