6. Jackson's poster is best described as a parallelogram because a parallelogram has opposite sides that are congruent and parallel.
7. The dimensions that could represent the side lengths of the isosceles triangle Ellen drew are 16, 16, 18 because the two equal sides are equal in length.
18. The measure of an angle that is complementary to a 47-degree angle is 43 degrees because complementary angles add up to 90 degrees.
22. To construct a perpendicular bisector, you will need a compass and a straightedge. Start by drawing a straight line segment. Use the compass to find the midpoint of the line segment by making arcs on either side that intersect the line. Then, adjust the compass to a larger radius and make arcs above and below the line at different points. Use the straightedge to connect the intersection points of these arcs, creating two lines that intersect at the midpoint of the original line segment. This line will be the perpendicular bisector.
6. To determine the shape of Jackson's poster, we need to identify the characteristics given. The fact that each pair of opposite sides are congruent and parallel tells us that the shape is a parallelogram. Therefore, the best answer is A. Parallelogram.
7. An isosceles triangle has two sides of equal length. Looking at the given options, we can see that option C, with side lengths of 16, 16, and 18, satisfies this criterion. Therefore, the answer is C. 16, 16, 18.
18. Complementary angles are two angles that add up to 90 degrees. If we have a 47-degree angle, we can find its complementary angle by subtracting its measure from 90 degrees: 90 - 47 = 43 degrees. Therefore, the complementary angle to a 47-degree angle is the answer A. 43 degrees.
Short Answer:
22. To construct a perpendicular bisector, follow these steps:
1. Draw a straight line segment that you want to find the perpendicular bisector for.
2. Take your compass and open it to a radius greater than half the length of the line segment.
3. Place the compass on one endpoint of the line segment and draw an arc that intersects the line segment.
4. Without changing the compass opening, place the compass on the other endpoint of the line segment and draw another arc that intersects the first arc.
5. Use a straightedge to connect the two points where the arcs intersect. This line is the perpendicular bisector of the original line segment.
