Geometry Angles • Identify angles as acute, right or obtuse • Find the measure of an angle using a protractor Angle Properties • Identify, estimate and measure the angles of plane figures using appropriate tools The Coordinate Plane • Use the coordinate system to describe the location and relative position of points and draw figures in the first quadrant Using the Coordinate Plane • Graph points on a coordinate plane • Identify quadrants • Locate the vertices of a shape on the coordinate plane • Find the area and perimeter of shapes Transformations • Identify, predict and describe the results of transformations of plane figures (reflections, rotations, translations) Transformations on the Coordinate Plane • Perform translations and reflections in the coordinate plane • Identify the mirror line in a reflection Properties of Quadrilaterals • Classify quadrilaterals by their sides and by their angles Triangle Classification • Identify, define, describe and accurately represent triangles Exploring Symmetry • Classify plane figures according to types of symmetry (line, rotational)
