Today we went over the last two circle theorems. We have been doing this all week and the rest of them are saved in the courswork drive.
Circle Theorem #6:
If a quadrilateral is cyclic, then the opposite angles are supplementary
*Meaning that the angles that are opposite each other always add up to 180 degrees.
Cirle Theorem #7:
If two lines are tangent to the same circle, and intersect in the exterior of the circle, then the line segments created by the point and points of tangency are congruent.
* So pretty much the lines are the same.
We then continued to do practice questions.
