To identify each quadrilateral, we look at the specific features shown in the drawings and match them to the definitions provided in the guide.
Step 1: Identify the first shape (left)
*
Observation: This shape has four sides. The top side and the bottom side are horizontal and parallel to each other. The left and right sides are slanted and are not parallel. It looks like a standard trapezoid.
*
Definition Match: The guide defines a
trapezoid as "a quadrilateral with exactly 1 pair of parallel sides."
*
Conclusion: This shape is a
trapezoid.
Step 2: Identify the second shape (middle)
*
Observation: This shape is tall and narrow. The opposite sides (top/bottom and left/right) appear to be parallel to each other. However, the corners do not look like square corners (right angles); they look slanted.
*
Definition Match: The guide defines a
parallelogram as "a quadrilateral with 2 pairs of parallel sides opposite each other." Since it doesn't have right angles (like a rectangle) or equal sides indicated (like a rhombus), it fits the general parallelogram category best.
*
Conclusion: This shape is a
parallelogram.
Step 3: Identify the third shape (right)
*
Observation: This shape is tilted. All four sides appear to be the same length. The opposite sides are parallel. The corners are not right angles (they are sharp and wide).
*
Definition Match: The guide defines a
rhombus as "a parallelogram with 4 congruent sides" (congruent means equal length). This matches the visual evidence perfectly.
*
Conclusion: This shape is a
rhombus.
Final Answer:
From left to right, the quadrilaterals are:
1.
Trapezoid
2.
Parallelogram
3.
Rhombus
