Orange Public Schools CCSS Curriculum CONTENT AREA: Mathematics # 1 2 3 4 5 Course: Geometry UNIT #: 4 UNIT NAME: Trig & Circles STUDENT LEARNING OBJECTIVES CORRESPONDING CCSS Derive the definitions for trigonometric ratios using similarity of right triangles. Use trigonometric ratios and to solve right triangles in applied problems.★ Identify and describe relationships among inscribed angles, radii, and chords. Include relationship between central, inscribed, and circumscribed angles and inscribed angles on a diameter are right angles. Construct tangent line from a point outside a given circle to the circle and describe the relationship of the angle formed by the radius of a circle and the line that is tangent to the point where the radius intersects the circle. Construct the inscribed and circumscribed circles of a triangle and prove properties of angles for a quadrilateral inscribed in a circle. Find the angle measures in degrees.

Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.★ Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle. Construct the inscribed and circumscribed circles of a triangle, and prove properties of angles for a quadrilateral inscribed in a circle. (+) Construct a tangent line from a point outside a given circle to the circle.
