Understanding Rectangle Construction
To construct a rectangle when two adjacent sides are known, option 'D' is indeed the correct method. Here’s why:
Step 1: Drawing One Side
- Begin by drawing one of the known sides on your drawing surface. Let's say this side is the length of the rectangle.
Step 2: Constructing a 90° Angle
- At one end of the drawn side, you need to form a right angle (90°). This can be done using a set square, or by employing a compass to create arcs that intersect at right angles.
- The construction of a 90° angle is crucial because rectangles require all interior angles to be right angles.
Step 3: Measuring the Adjacent Side
- From the point where the right angle is formed, measure out the length of the adjacent side (width of the rectangle) along the line created by the 90° angle.
Step 4: Completing the Rectangle
- Repeat the process at the other end of the original side, drawing another 90° angle and measuring out the adjacent side.
- Finally, connect the ends of these two lines to complete the rectangle.
Key Takeaways
- Constructing a rectangle fundamentally relies on the ability to create and measure right angles.
- This method ensures that all angles are precisely 90°, which is essential for the shape to be classified as a rectangle.
By following these steps, you can effectively and accurately construct a rectangle using the known lengths of two adjacent sides.

When constructing a rectangle given two adjacent sides, you first draw one side of the rectangle. At one endpoint, you construct a 90° angle to establish the second side. After marking the length of the second side, you can then use arcs to find the opposite corners and complete the rectangle. This method emphasizes the properties of rectangles, particularly the right angles at each vertex.
