Transcript
Mathematics Grade Seven – Pre-Algebra - Unit 9 Spatial Thinking Essential Understandings: Geometry and Measurement• name basic geometric figures • recognize intersecting lines, parallel lines, and skew lines • identify adjacent and vertical angles • relate angles formed by parallel lines • classify triangles and quadrilaterals • use “draw a diagram” as a problem solving strategy • identify congruent triangles • find the circumference • create circle graphs • construct a segment or an angle congruent to a give segment or angle • describe and graph translations • identify lines of symmetry • graph a reflection or rotation of a geometric figure • identify rotational symmetry Content Vocabulary: Adjacent angle Alternate interior angles Angle bisector Complementary Congruent angles Congruent figures Corresponding angles Parallel Perpendicular bisector Perpendicular lines Polygon Supplementary Reflection Symmetry Rotation Translation Segment Vertical angles
