(x - a)^2 + (y - b)^2 = r^2 (centre is at point a, b and radius of r)
Opposite/vertical angles
Give this one a try later!
Created when two lines intersect at a point. Opposite angles have
equal measures, and angles that have equal measures are called
congruent angles. Hence, opposite angles are congruent. The sum of
the measures of the four angles is 360.
