4.7 Ángulos y medidas de ángulos

Unit Goals

  • Students learn to draw and identify points, rays, segments, angles, and lines, including parallel and perpendicular lines. Students also learn how to use a protractor to measure angles and draw angles of given measurements, and identify acute, obtuse, right, and straight angles in two-dimensional figures.

Section A Goals

  • Draw and identify points, lines, rays, segments, and parallel and intersecting lines in geometric figures.
  • Recognize that angles are formed wherever two rays share a common endpoint and identify angles in two-dimensional figures.

Section B Goals

  • Recognize that angles can be measured in degrees, and can be found using addition and subtraction.
  • Use a protractor to measure and draw angles, and recognize that perpendicular lines meet or cross at a right angle.

Section C Goals

  • Draw and identify acute, obtuse, right, and straight angles in two-dimensional figures.
  • Write equations to represent angle relationships and reason about and find unknown measurements.
