Common Core Aligned Resources for HSG-C.A.2
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.

Module 5: Circles A Geometric Perspective
9th - 12th CCSS: Designed
New ReviewCircles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...
Spinning an Old Record
11th - 12th CCSS: Adaptable
New ReviewTake a trip back in time to examine angular velocity. Using the revolutions per minute, learners calculate the speed of a point on a 33 record. They compare the speed of a point on the edge of the record to the speed of a point closer to...
Module 1: Transformations and Symmetry
9th - 12th CCSS: Designed
New ReviewNo need to change anything about the resource. The first of eight modules in the MVP Geometry unit focuses on transformations in the coordinate plane. It connects translations, rotations, and reflections to congruence, symmetry, and...
Angles Outside a Circle: Lesson
3 mins 6th - 12th CCSS: Adaptable
Understand the difference in finding angle measures. A segment of an extensive geometry playlist introduces the formula to find the measure of an angle formed outside of a circle. Using examples, the video shows how to calculate measures...
Inscribed Angles in Circles: Lesson
6 mins 9th - 12th CCSS: Adaptable
Circle the angles and intercept the arcs. The video introduces three theorems relating to inscribed angles in circles. Using drawings, the segment of a playlist on geometry illustrates the measure of angle along with theorems about two...
Inscribed Quadrilaterals in Circles: Lesson
2 mins 9th - 11th CCSS: Adaptable
Find supplementary information about inscribed angles. A section of a large geometry playlist introduces the relationship of angles in an inscribed quadrilateral. The presentation works through examples that use the relationship between...
How Do You Find the Center of a Circle?
4 mins 9th - 12th CCSS: Adaptable
The center of the circle is the center of attention for the resource. A brief video in the Socratica Geometry playlist shows how to find the center of a circle not on the coordinate plane. The method here is to construct the...
