Find the equation of the following parabola. a) b) c) d) EOCT Practice d
Case I:Vertex is AT the center A P C B
Case II:Vertex is ON circle ANGLE ARC ARC ANGLE
Ex. 1 Find m1. 1 84° m1 = 42
202° Ex. 2 Find m1. 1 m1 = 79
Case III:Vertex is INSIDE circle A ARC B ANGLE D ARC C Looks like a PLUS sign!
Ex. 3 Find m1. 93° A B 1 D C 113° m1 = 103
Ex. 4 Find mQT. mQT = 100 N Q 84 92 M T
Ex. 5 Find x. 93 xº 45 89 x = 89
