Answer all them list them in order and show work in a simple understandable way

Solution

I have displayed the image for analysis. Now, let's address each of the quiz questions in order.

1. Give two names for the plane.

  • Based on the diagram, the plane can be named using three non-collinear points in the plane.
    • Two possible names are:
      • Plane ABC
      • Plane ABD

2. Name three collinear points.

  • Collinear points are points that lie on the same straight line.
    • Points A, B, and C are collinear.

3. Name three coplanar points.

  • Coplanar points are points that lie on the same plane.
    • Points A, B, and D are coplanar.

4. Name three points.

  • You can select any three points from the diagram. For example:
    • Points A, B, and D.

5. Name one ray.

  • A ray starts from one point and goes infinitely in one direction.
    • Ray AB (starting at A and passing through B).

6. Name two lines.

  • From the diagram, two lines can be named:
    • Line AC
    • Line BD

7. Name one line segment.

  • A line segment has two endpoints.
    • Line segment AB.

8. Sketch the figure described: AB and AC.

  • This requires drawing the two rays AB and AC, which share the same starting point A and move in different directions.

9. Plane C and plane D intersecting at XY.

  • This suggests that two planes intersect at line XY. You can visualize this as a line where two flat surfaces meet.

10. Find BD.

  • Based on the work shown on the page, BD is given as 17.

11. The endpoints of QR\overline{QR} are Q(1,6) and R(7,3). Find the coordinates of the midpoint M.

  • To find the midpoint M(x,y)M(x,y) of a segment with endpoints (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2), use the midpoint formula: M=(x1+x22,y1+y22)M = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right) Substituting: M=(1+72,6+32)=(4,4.5)M = \left(\frac{1 + 7}{2}, \frac{6 + 3}{2}\right) = (4, 4.5) So, the midpoint MM is (4,4.5)(4, 4.5).

12. Find the distance between the two points S(-5, -2) and T(7, 4).

  • Use the distance formula: d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} Substituting: d=(7(5))2+(4(2))2=(12)2+(6)2=144+36=180d = \sqrt{(7 - (-5))^2 + (4 - (-2))^2} = \sqrt{(12)^2 + (6)^2} = \sqrt{144 + 36} = \sqrt{180} So, d=180=13.42d = \sqrt{180} = 13.42 (rounded to two decimal places).

13. Identify the segment bisector of QR\overline{QR}.

  • The bisector of a segment divides it into two equal parts. Based on the diagram, the bisector seems to be a line passing through the midpoint of QR\overline{QR}.

14. Find the coordinates of endpoint H if the midpoint of GH\overline{GH} is M(4, -3) and G is (2, 4).

  • Use the midpoint formula to find the missing endpoint H(x2,y2)H(x_2, y_2). We know the midpoint formula is: M=(x1+x22,y1+y22)M = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right) For the x-coordinate: 4=2+x22    8=2+x2    x2=64 = \frac{2 + x_2}{2} \implies 8 = 2 + x_2 \implies x_2 = 6 For the y-coordinate: 3=4+y22    6=4+y2    y2=10-3 = \frac{4 + y_2}{2} \implies -6 = 4 + y_2 \implies y_2 = -10 Therefore, the coordinates of HH are (6,10)(6, -10).

Feel free to ask for more details or clarification!

Here are 5 related questions to deepen your understanding:

  1. What is the difference between a ray and a line?
  2. How do you determine if points are collinear?
  3. What is the difference between coplanar and collinear points?
  4. How do you find the equation of a line given two points?
  5. What is the relationship between the segment bisector and the midpoint?

Tip: Always double-check your substitution in formulas like the distance or midpoint formulas to avoid simple mistakes.
