• Secant of an angle is the length of the secant line from the center of the circle to the opposite tangent. • Cosecant of an angle is the length of the secant line from the center of the circle to the adjacent tangent (cotangent). • Complementary angles: Two angles that add up to 90°. • Perpendicular lines: Lines that meet at an angle of 90°.
