Lesson Plan –Geometry
Teacher: Clark
Period(s): 2nd
State competency goal and objective:
Start date: 1-03
End date: 1-06
2.03 Apply properties, definitions, and theorems of two-dimensional figures to solve problems and write proofs: d) Circles.
EQ:
How do you use the properties of tangents and chords to find missing measures in circles?
How do you use central angles to find arc measures?
How do you use inscribed angles to find missing measures in circles?
How do you use circumference to find arclength?
Literacy enhancements/Key Vocabulary:
circle center radius diameter chord tangent tangent circles common tangent internally tangent externally tangent point of tangency
inscribed circumscribed concentric circles congruent circles secant major arc inscribed angle intercepted arc minor arc semicircle central
angle circumference pi arclength external segment tangent segment secant segment chord segment
Adaptations/Differentiation:
