I can distinguish between polygons and non polygons
Polygon or non polygon? Use properties to explain your answer. It is enclosed and has at least straight sides
Polygon or non polygon? Use properties to explain your answer. Not a Polygon – It doesn’t have straight sides
Polygon or non polygon? Use properties to explain your answer. It is enclosed and has at least straight sides
Polygon or non polygon? Use properties to explain your answer. Not a Polygon – Sides of a polygon aren’t allowed to cross
Polygon or non polygon? Use properties to explain your answer. Not a polygon Doesn’t have straight sides
Polygon or non polygon? Use properties to explain your answer. It is enclosed and has at least straight sides
I can identify a polygon by the number of sides.
Name this Polygon Explain how you know by the number of sides Triangle – It is a polygon with 3 sides
Hexagon – It is a polygon with 6 sides Name this Polygon Explain how you know by the number of sides Hexagon – It is a polygon with 6 sides
Name this Polygon Explain how you know by the number of sides Octagon – it is a polygon with 8 sides
Name this Polygon Explain how you know by the number of sides Quadrilateral because it has 4 sides
Name this Polygon Explain how you know by the number of sides Pentagon because it has 5 sides
I can identify various types of quadrilaterals by examining their properties
Name this Quadrilateral Use your knowledge of properties to support your answer. Parallelogram – It has opposite sides that are parallel and equal
Name this Quadrilateral Use your knowledge of properties to support your answer. Rhombus– It has opposite sides that are parallel and all sides are equal
Use your knowledge of properties to explain why this is a SQUARE It is a rectangle that has all equal sides
Trapezoid – It has ONE set of parallel lines Name this Quadrilateral Use your knowledge of properties to support your answer. Trapezoid – It has ONE set of parallel lines
It has opposite sides are equal and parallel Use your knowledge of properties to explain why this is a PARALLELOGRAM It has opposite sides are equal and parallel
Parallelogram – It has opposite sides that are parallel Name this Quadrilateral Use your knowledge of properties to support your answer. Parallelogram – It has opposite sides that are parallel
Use your knowledge of properties to explain why this is a RHOMBUS It is a parallelogram with 4 sides that are equal
Use your knowledge of properties to explain why this is a RECTANGLE It is a parallelogram that has 4 right angles
Polygon or non polygon? Use properties to explain your answer. Is this a parallelogram? Use your knowledge of properties to support your answer. Polygon or non polygon? Use properties to explain your answer.
Polygon or non polygon? Use properties to explain your answer. Is this a parallelogram? Use your knowledge of properties to support your answer. Polygon or non polygon? Use properties to explain your answer.
Polygon or non polygon? Use properties to explain your answer. Is this a parallelogram? Use your knowledge of properties to support your answer. Polygon or non polygon? Use properties to explain your answer.
Polygon or non polygon? Use properties to explain your answer. Is this a quadrilateral? Use your knowledge of properties to support your answer. Polygon or non polygon? Use properties to explain your answer.
Trapezoid – It has ONE pair of parallel sides Name this Quadrilateral Use your knowledge of properties to support your answer. Trapezoid – It has ONE pair of parallel sides
Polygon or non polygon? Use properties to explain your answer. Is this a parallelogram? Use your knowledge of properties to support your answer. Polygon or non polygon? Use properties to explain your answer.
Why is this polygon NOT a quadrilateral? It has six sides, not four
Why is this quadrilateral NOT a parallelogram It doesn’t have opposite sides that are parallel and equal
I can identify various geometric figures
What is this figure called? Ray
What are these figures called? Parallel lines
What is this figure called? Angle
What is the special name for Point V? Vertex
I can distinguish between right angles, obtuse angles and acute angles
What kind of angle is this – right, obtuse or acute? Right Angle
Explain why this is a right or 90 degree angle It measures exactly 90 degrees
What kind of angle is this – right, obtuse or acute? Obtuse Angle
Explain why this is an obtuse angle The angle is larger than 90 degrees
What kind of angle is this – right, obtuse or acute? Acute Angle
Explain why this is an acute angle The angle is less than 90 degrees
Explain why this is called a right triangle. It has an angle that is exactly 90 degrees
