PolygonsTriangles Perimeter and Area Quadrilaterals

Which of the following does NOT describe a polygon? Two-dimensional Open figure Straight sides Rounded lines Open figure, rounded lines

What polygon has seven sides, seven vertices, and seven angles? Heptagon

Which shape below is not a polygon? Why? A. B. C. B- The figure is open, not closed.

A stop sign is in the shape of what polygon? Octagon

What polygon is the shape below? Pentagon

What are the three ways a triangle can be classified by its angles? Right, acute, obtuse

What does it mean for a triangle to be classified obtuse and scalene? It has one obtuse angle (greater than 90°) and no congruent sides

What belongs in the graphic organizer below? A- scalene B- equilateral Triangles ObtuseRightAcute A? IsoscelesB?

Classify the triangle below by its sides and angles: Isosceles, acute

Is an equilateral triangle also an isosceles triangle? Why? Yes, because an isosceles triangle has at least two congruent sides, and an equilateral triangle has all 3 congruent.

What quadrilateral has only one pair of parallel sides? Trapezoid

Rhombus Quadrilateral What shape belongs in the graphic organizer below? Parallelogram Trapezoid Rectangle? Square

What quadrilateral has opposite angles congruent and all angles 90°? Rectangle

What are all possible classifications of the shape below? (Hint: There are 5.) Quadrilateral, parallelogram, rectangle, rhombus, square

Can a quadrilateral be both a trapezoid and a parallelogram? Why? No, because a trapezoid has only 1 set of parallel lines and a parallelogram has 2 sets of parallel lines

Does the problem below ask for area or perimeter? Mike is making a picture frame out of yarn for mother’s day. The picture he wants to use is 4 inches by 6 inches. How much yarn does he need for the picture frame? Perimeter

What are the two dimensions of rectangles? Length and width

What is the perimeter of the shape below? 12 centimeters 4 cm 2 cm

What is the area of the shape below? 189 square feet 21 ft 9 ft

What is the length of the each side of the square below if the area is 36 inches? 9 inches A=36 square inches ? ? ? ?
