WebStep 2: Use what we learned from Case A to establish two equations. In our new diagram, the diameter splits the circle into two halves. Each half has an inscribed angle with a ray on the diameter. This is the same situation as Case A, so we know that. (1)\quad\purpleC {\theta_1}=2\blueD {\psi_1} (1) θ1 = 2ψ1. and. WebUsing the unit circle diagram, draw a line “tangent” to the unit circle where the hypotenuse contacts the unit circle. This line is at right angles to the hypotenuse at the unit circle and touches the unit circle only at that point (the tangent point). Extend this tangent line to the x … WebExplore, prove, and apply important properties of circles that have to do with things like arc length, radians, inscribed angles, and tangents.
