Instructional Content and Strategies Organizer Instructional Content • A referent for a 45° angle is the angle created by a diagonal of a square and one of the sides of the square that share a common vertex. • A referent for a 90° angle (right angle) is the angle created by the corner of a square. • A referent for a 180° angle (straight angle) is the angle created by a straight line. • Protractors and angle rulers are tools commonly used to measure angles. • An acute angle has a measure between 0° and 90°. • A right angle (square angle) has a measure of 90°. • An obtuse angle has a measure between 90° and 180°. • An acute triangle has three acute angles. • A right triangle has one right angle and two acute angles. • An obtuse triangle has one obtuse angle and two acute angles.
