Tuesday Nov.27

Hey everyone..
Today in math we continued working on circle geometry.

We started with circle number 3.
*If a circle contains an inscribed angle such that the angle intercepts a semicircular arc, THEN the inscribed angle has a measure of 90 degrees.
(Inscribed- when a line intercepts a semi-circle.)

Circle-4 If 2 angles are inscribed in the same circle and they both intercept the same arc THEN, they are congruent.
(Congruent- the same)

Circle 5- If there exists a line tangent to a circle THEN the tangent line is perpendicular to the radius/diameter at the point of tangency.
(Tangency- having contact at a single point or along a line without crossing.)

Circle 6- If a point in the exterior of a circle and 2 unique lines tangent to that circle exist through that point then the segments created from the points of tangency to the exterior point must be congruent.

That was the lesson for the day after that we continued working on accelerated math.
* The new deadline for accelerated math is next Tuesday!
Have a great week. The next scribe is Toderash
