Описание:
• 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°.
