Options:
a. polygon
b. hexagon
c. open shape
d. quadrilateral

Answer: a. Polygon

Explanation: In geometry, a polygon is a plane figure that is described by a finite number of straight-line segments connected to form a closed polygonal chain or polygonal circuit.

Question 2.
Sam drew one side of a rhombus with at least 1 right angle. Draw the other 3 sides to complete Sam’s shape.

Explanation:

A rhombus is a Parallelogram with 4 equal sides. Because it is a parallelogram, opposite angles are congruent. And because it is a quadrilateral the sum of all angles must be equal to 360 degrees. So, if one angle is right then the opposite angle is 90 degrees. Then the 1^st pair has a sum of 180 degrees, then 360–180 = 180, so the other pair of angles sum to 180 degrees. But the other pair of angles are also opposite of eac
