Question 1190408: For a project in her Geometry class, Madeline uses a mirror on the ground to measure the height of her school building. She walks a distance of 9.45 meters from the building, then places a mirror flat on the ground, marked with an X at the center. She then walks 2.75 more meters past the mirror, so that when she turns around and looks down at the mirror, she can see the top of the school clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.55 meters. How tall is the school? Round your answer to the nearest hundredth of a meter.

Question 1192149: 1. Let be five points, no three of which are collinear. How many lines contain two of these five points?
2.If no four of the five points are coplanar, how many planes contain three of the five points?
Hint: (for 1 and 2, list all the lines and the planes as sets)
3.Suppose you have n points, no three of which are collinear. How many lines contain two of these n points?
4.If no four of the n points are coplanar, how many planes contain three of the n points?
Hint: (for 3 and 4, generalize in a form of a formula)
5.Prove theorem 1.1.4. The steps in the proof are already given: you just have to supply the reasons for each step.
Theorem 1.1.4. If two lines intersect, then their union lies in exactly one plane.
Proof: Let and be two intersecting lines.
∩ is a point p.
contains a point q ≠ p.
There is a plane E, containing and q.
E contains ∪ .
No other plane contains ∪ .

Question 1193730: Use the following image to answer the questions below:
a. What information would you need to determine if the figure is a parallelogram? Name multiple ways to determine if the figure is a parallelogram.
b. What information would you need to determine if the figure is a rhombus? A square? A rectangle?
c. Two of your friends are arguing: Marlon argues that a parallelogram is also a trapezoid; Tamara argues that a parallelogram is not a trapezoid. List some of the reasons Marlon might argue that parallelograms are also trapezoids based on the similarities between the figures.
d. List some of the reasons Tamara might argue that parallelograms are not trapezoids based on the differences between the figures.
