What is the difference between a line and a line segment?
A line goes on forever and a line segment has endpoints.
200
<PQR is a right angle and ray QS is bisecting <PQR. What is the value of m<PQS.

<1 and <5 or <4 and <8
400

400

400
Lines AB and CD intersect at point E. If m<AEB=6x+2 and m<BED=8x-12, what is the value of m<CEB.
112
400
Lines m and n are parallel. Name all pairs of vertical angles.
<1 and <7, <2 and <8, <3 and <5, <4 and <6
500

500
Draw segment ABC on your whiteboards where B is the midpoint. Make segment AB = 2x+4. Make your own equation for segment BC (that is different from AB) that will make segment AC=48.
x=10 so some equation where if x=10, the answer is 24 that is not 2x+4. Some examples are x+14, 3x-6, 4x-16, etc.
500
What is a linear pair?
Two adjacent angles that are supplementary.
