EOC Review Question of the Day

Secant and Tangent Angles Vertex is INSIDE OR OUTSIDE the circle

Wheel of Formulas!!

Vertex is INSIDE the Circle NOT at the Center

Ex. 1 Solve for x 180 – 88 X 88º 84º 92 x = 100

Ex. 2 Solve for x. 360 – 89 – 93 – 45 45 93 xº 89 133 x = 89º

Ex. 3 Find m1. 93° A B 1 D C m<1 = 103º 113°

Ex. 4 Find mQT. N Q 84 92 M T mQT = 100º

Ex. 5 Find x. 93 xº 45 89 x = 89º

Vertex is OUTside the Circle

Ex. 1 Solve for x. x 15° x = 25º 65°

Ex. 2 Solve for x. 27° x 70° x = 16º

Ex. 3 Solve for x. 360 – 260 260° 100 x x = 80º

Tune: If You’re Happy and You Know It If the vertex is ON the circle half the arc. <clap, clap> If the vertex is IN the circle half the sum. <clap, clap> But if the vertex is OUTside, then you’re in for a ride, cause it’s half of the difference anyway. <clap, clap>
