Constructing Quadrilaterals and Coordinates

The video tutorial guides viewers through creating a quadrilateral using four given coordinates. It starts by introducing the concept of a quadrilateral and the importance of vertices. The instructor then demonstrates how to plot each point on a coordinate plane, ensuring each vertex is correctly placed. Finally, the points are connected to form a complete quadrilateral, emphasizing the geometric principles involved.

What is the first step in constructing the quadrilateral?

• Place a vertex at the point (0, 9)

• Draw a circle with a radius of 9

• Connect all the given points

• Identify the midpoint of the line segments

Which coordinate is used for the second vertex of the quadrilateral?

• (0, 9)

• (0, -7)

• (8, 0)

• (8, -7)

Where is the third vertex of the quadrilateral placed?

• (8, 0)

• (8, -7)

• (0, 9)

• (0, -7)

What is the final coordinate used to complete the quadrilateral?

• (8, 0)

• (8, -7)

• (0, -7)

• (0, 9)

What is the final step in constructing the quadrilateral?

• Rearrange the points

• Connect the vertices

• Calculate the area

• Measure the angles

How many sides does the figure have once completed?

• Three

• Six

• Four

• Five
