![]() ![]() Trisecting an Angle: To trisect an angle is to use the same procedure as bisecting an angle, but to use two lines and split the angle exactly in thirds. This is possible using a compass and an unmarked straightedge. They share the same degree value.īisecting an Angle: To bisect an angle is to draw a line concurrent line through the angle's vertex which splits the angle exactly in half. \(\measuredangle HRS, \, \measuredangle RST\) are alternate interior angles. They share the same degree value.Īlternate interior angles (Z property): Angles which share a line segment that intersects with parallel lines, and are in opposite relative positions on each respective parallel line, are equivalent. ![]() \(\measuredangle IRQ, \, \measuredangle KUQ\) are corresponding angles. They share the same degree value.Ĭorresponding angles (F property): Angles which share a line segment that intersects with parallel lines, and are in the same relative position on each respective parallel line, are equivalent. \(\measuredangle JSR, \, \measuredangle OST\) are vertical angles. Vertical angles (X property): Angles which share line segments and vertexes are equivalent. \(\measuredangle JSN, \, \measuredangle NSK\) are supplementary angles. \(\measuredangle PRQ, \, \measuredangle QRI\) are complementary angles. \(\measuredangle HRL, \, \measuredangle HRO\) are adjacent.Ĭomplementary angles: add up to 90°. Obtuse angle: Angles which measure > 90° - \(\measuredangle CDE\)Īcute angle: Angles which measure 180°, which adds to an angle to make 360° - \(\measuredangle CDE\)'s reflex angle is \(\measuredangle CDF + \measuredangle FDE\)Īdjacent angles: Have the same vertex and share a side. Right angle: Angles which measure 90° - \(\measuredangle ABC\) ![]() Normally, Angle is measured in degrees (\(^0\)) or in radians rad). ![]()
