Geometry flashcards! Your students will learn the properties of various triangles and quadrilaterals as they draw shapes on these polished, no-prep triangle flash cards and quadrilateral flash cards aligned to the Common Core. Geometric 2D figures include equilateral triangle, isosceles triangle, scalene triangle, right triangle, square, rectangle, rhombus, parallelogram, and trapezoid. Your students will learn that all squares are rectangles, all equilateral triangles are isosceles triangles, etc. These geometry flash cards can serve as a great reference throughout your geometry unit or as a tool for studying.
Answer key is included.
Aligned to 4th Grade Common Core Standards
• 4.G.A.2 - Classify two-dimensional figures based on the presence or absence of parallel
or perpendicular lines, or the presence or absence of angles of a specified size.
Recognize right triangles as a category, and identify right triangles.
Aligned to 5th Grade Common Core Standards
• 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.
• 5.G.B.4 - Classify two-dimensional figures in a hierarchy based on properties.
