100

The intersection of two planes

What is a line?

200
Part of a line that has one endpoint and extends out indefinitely in one direction.
What is a ray?
200
Given segment AC and a point B between A and C. If AB=3 and AC=15, find the length of BC.

200
The distance between the points X(21, 5) and Y(28, -1).
What is the square root of 85 OR 9.2?

Define Perimeter and Area

What is...

Perimeter is distance AROUND a figure (1- dimensional)

Area is the space INSIDE a figure (2-dimensional)

200

PART + PART = WHOLE is a simpler way to describe a postulate regarding segments.

What is Segment Addition Postulate?


300

Look at the last example in your 1.1 Notes. A line that is coplanar with Plane V.

What is... Many answers! Line f, line RQ, QR, QS, SQ RS or SR. Incorporating point T is also allowed since it is on the plane.

300
The value of the variable if P is between J and K, JP = 2x, PK = 7x, and JK = 27.
What is x = 3?
300
Any segment, line, or plane that intersects a segment at its midpoint.
What is a segment bisector?
300

The formulas we can use to calculate the length of the segment with endpoints represented as coordinates.

What is distance formula OR Pythagorean theorem if given a graph.

300

Where two sides meet.

What is a vertex?

400

Geometric figures that are UNDEFINED.

What is points, lines, and planes?

400
The value of the variable if P is between J and K, JP = 8x-17, PK = 5x+37, and JK = 17x-4.
What is x = 6 ?
400
The coordinates of the midpoint of the segment containing points R(-11, 34) and S(47, 0).
What is (18, 17) ?
400

The area of the polygon with the given vertices:

W(0,0), X(0,3), Y(-3,3), Z(-3,0)

What is 9 square units?

400

The average of 8, 3, 14, and 7.

What is 8?

500

Look at the last example in our 1.1 Notes. A name for a set of opposite rays (name both RAYS).

What is QR and QS?

500

We can refer to a segment AB with or without the segment notation (the line above the two letters).

When do we use the notation and when do we not?

We use the segment notation when we are referring to geometric properties of segments (their relationship with other segments and objects).

The notation is NOT used for numerical calculations.

500
The coordinates of missing endpoint A, if M(15, 4) is the midpoint of segment AB and B has coordinates (-11, -6).
What is (41, 14) ?
500

Find the perimeter of the polygon with the given vertices:

G(2,4), H(2,-3), J(-2,-3), K(-2,4)

What is 22 units?

500

The weighted average of 5 with a weight of 4, 3 with a weight of 6, and 12 with a weight of 2. Round answer to the TENTH (one decimal place).

What is 5.2?
