What's The Word?
This is a location. It has neither size nor shape, only position
Point
Name a point contained in line n (slide 8)
E or B
This is where two lines intersect
A point
AC is this long (slide 9)
2 meters
On a field trip, a bus driver was told to make a stop 53 miles into the trip. If the rest of the trip is 41 miles and the entire journey can be represented by the expression 3x + 16, then the value of x would be this.
x = 26
If two points are on the same line, they are called this.
Collinear
Name the plane (slide 2)
Plane B
These kinds of lines never intersect.
Parallel lines
True or false: XY≅WZ (slide 4)
This is the value of x (slide 10)
x = 9.5
This is a flat surface up of points that has no depth and extends indefinitely in all directions.
Plane
Name a line that contains point E (slide 8)
q
The coordinate of point X on PQ that is 3/4 of the distance from P to Q is this. (slide 6)
4
The coordinates of A and B are –7 and 9. The coordinates of C and D are –4 and 12. This is their length.
16 units
Houses A, B, and C are in a straight line. The distance between House A and House B is 3x + 2 miles. The distance between House B and House C is 3x + 4 miles. The distance between House C and House A is 9x - 3 miles. Using the value of x, we know that THIS is the distance between Houses A and C.
x = 3
AC = 24 miles
This word is used to describe constructions that are equal in every possible measurement.
Congruent
Name a line using three collinear points (slide 3)
Line AEC or CEA
This geometric construction is created when two planes intersect
A line
On a straight highway, the distance from Loretta’s house to a park is 43 miles. Her friend Larry lives along this same highway between Loretta’s house and the park. From Loretta’s house to Larry’s house is 31 miles. The distance from Larry’s house to the park is this many miles.
12 miles
Find the value of x given the following information.
Q is between P and R;
PQ=5x−10;
QR=3(x+4);
PQ ≅ QR
x=11
You would use this type of geometry to perform calculations on this figure (slide 1)
Synthetic Geometry
Name four points that are coplanar (slide 7)
ABEF, FADC, CBDE
These kinds of lines intersect at a 90 degree angle
Perpendicular lines
During the archaeological dig of a shipwreck near St. Augustine, a bronze bell and a pewter spoon were found this far apart (slide 5)
About 14.9 feet (or square root of 221)
What are the values of x and BC given the following information?
B is between C and D;
CB = 2x;
BD = 4x; and
CD = 12.
x = 2
BC = 4
