In the diagram on the board, find the measure of angle A if angle B= 135 degrees * THERE WILL BE A DIAGRAM ON THE BOARD*
What is A+B= 180 degrees A+135= 180 degrees A= 180-135 degrees A= 45 degrees

What is a point?
A point is a location in space and it has no size.

What is the difference between a line and a line segment?
What is A line has no end and a line segment has two endpoints so it does have an end.
200
Draw an example for each angle: obtuse angle acute angle right angle straight angle
What is We will come around and see if you have the right angles drawn.

Name three shapes that are quadrilaterals.
What is a rectangle, a square, a rhombus, a trapezoid, a parallelogram
200
Change each percent into degrees to put into a pie graph, also called circle graph. YOU DO NOT HAVE TO MAKE A GRAPH!! Just change the percents into degrees. 25% 15% 20%
What is 25%= 90 degrees 20%= 72 degrees 15%= 54 degrees

Define the word polygon.
What is A polygon is a closed figure with at least three sides.
300
<----o-----------o---------------o----> *The o's indicate the points.* How many rays are there? How many points are there? How many line segments are there?
What is 4 different rays 3 different points 3 different line segments
300
* There will be a diagram on the board* If angle 8=20 degrees, find the measures of angle 5, angle 6, and angle 7.
What is angle 5= 160 degrees angle 6= 20 degrees angle 7= 160 degrees

Define the word skew.
What is Skew lines are lines that do not lie in the same plane.
400
What is a ray? Please draw an example.
What is A ray is a part of a line with exactly one end point.

A new student has just walked into the classroom. You need to explain to that student what a way to remember all the angles: acute,obtuse,right,and straight
What is every group will get a point for this question, if you answered it, because there is no right or wrong answer.

A.R.O.E.I.S. This is an abbervation for triangles in the textbook. Try to figure out what triangle each letter is.
What is A= acute triangle R= right triangle O= obtuse triangle E= equilateral triangle I= isosceles triangle S= scalene triangle
400
What is the formula of finding a circumference of a circle?
What is C= pi times the diameter
400
Define the word regular polygon.
What is A regular polygon has all sides congruent and all angles congruent.
500
Sally drew a line that had looked liked this: <-------o----------------o---------------o------> * the o's stand for points* She said that this line contained 3 points, 4 different segments, and 3 different rays What did she do wrong?
What is She mixed up the line segments with the rays, so the real answer is 3 points, 3 different segments, 4 different rays
500
What is a transversal?
What is A transversal is a line that intersects two other lines in different points.
500
I can be any shape you would like..... but it has to be four sides...... it also has to be a closed figure..... What am I?
