Standards 5.G.B.3 and 5.G.B.4


Standard 5.G.B.3

Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.

Vocabulary for this Standard:

• acute angle • acute triangle • congruence/congruent • equilateral triangle • hexagon • irregular polygon • isosceles triangle (first word is spelled incorrectly) • kite • obtuse angle • parallel lines • parallelogram • pentagon • perpendicular lines • plane figure • polygon • quadrilateral • rectangle • regular polygon • right angle • right triangle • rhombus/rhombi • scalene triangle • square • triangle • trapezoid • two-dimensional • vertex

Suggested Activities on IXL for standard 5.G.B.3 - Section BB

Standard 5.G.B.4

Classify two-dimensional figures in a hierarchy based on properties. For example, all rectangles are parallelograms because they are all quadrilaterals with two pairs of opposite sides parallel.
