What needs to be corrected in the following construction for copying ∠ABC with point D as the vertex?

Answers

To construct an angle bisector for ∠ABC, use a compass and straightedge to create intersecting arcs, connecting the vertex with the intersection point to form the bisector. Avoid changing compass width or inaccurate arc intersections.

Constructing an angle bisector for ∠ABC using only a compass and a straightedge involves a series of precise steps. Here are the instructions along with common mistakes to avoid:

Step-by-Step Instructions:

Draw ∠ABC: Begin by drawing the angle ∠ABC with the given vertex at point B.

Place Compass at Point B: Use your compass and place its needle point (the sharp end) at point B, the vertex of the angle.

Adjust Compass Width: Open the compass to a width that allows you to draw two arcs that intersect both rays of the angle. Ensure the compass width remains fixed during the construction.

Draw Arcs: With the compass set, draw an arc that intersects the first ray, AB. Keep the compass needle fixed at B, and draw another arc that intersects the second ray, BC. Label the points of intersection with the rays as D and E.

Connect B and E: Using your straightedge, draw a straight line that connects point B and point E.

Bisect the Angle: The line BE bisects angle ∠ABC, creating two equal angles, ∠ABE and ∠EBC. Angle ∠ABE is the bisector of ∠ABC.

Common Mistakes to Avoid:

Changing Compass Width: Keeping the compass width consistent is crucial. Changing it during the construction will result in an inaccurate angle bisector.

Inaccurate Arc Intersection: Ensure that the arcs drawn from points B intersect the rays AB and BC accurately at points D and E. Inaccurate intersection points will lead to an incorrect angle bisector.

Not Labeling the Bisector: It's essential to label the constructed angle bisector (∠ABE) to distinguish it from the original angles.

By following these steps carefully and avoiding common mistakes, you can accurately construct an angle bisector for ∠ABC using only a compass and a straightedge.

The endpoints of AB are A(9,4) and B(5,-4). The endpoints of its image after a dilation ar A(6,3) and B(3,-3). a. explain how to find te scale factor. b. locate the center of dilation. show your work

Answers

Look at the picture for the answer.

Final answer:

The scale factor of the dilation is calculated by dividing the length of the line after dilation by the length of the initial line. The length of a line is calculated using the distance formula. The center of dilation is the point from which the shape scales, but we can't determine its location without more information.

Explanation:

To find the scale factor of a dilation in a two-dimensional plane, we divide the length of the line after dilation by the length of the initial line. The length of a line can be calculated using the distance formula which is √[(x₂ - x₁)² + (y₂ - y₁)²].

For AB, the distance will be √[(5 - 9)² + (-4 - 4)²] = √[(-4)² + (-8)²] which equals √80. For A'B', the distance will be √(3 - 6)² + (-3 - 3)² = √[(-3)² + (-6)²] which equals √45. The scale factor (k) of the dilation is the ratio of these distances, so k = √45 / √80 which simplifies to √(9/16) or 3/4.

Unfortunately, without more information, such as a fixed point in the original shape, we can't determine the exact location of the center of dilation. But, conceptually, it's the point that the shape is scaling towards or away from during the dilation.
