What is a line?
is a straight path that has no thickness and extends forever in opposite directions.
100
What is 5:00 angle?
obtuse
100
Use Figure B. What is angle 2? What rules did you use?
120---adjacent to get angle 4 and then corresponding to angle 2. Answers may vary
100
All the angles in a triangle add up too? if one angle in a triangle is 27 and the other is 13, what does the last angle have to be?
180.....140.
100
Use Figure C. Are they Congruent? Why or not?
Yes because there side measures on each corresponding side are the same
200
What is a part of a line or ray that extends from one endpoint to another?
Line Segment
200
Draw an estimated angle of measure of 85 degrees. Then label the angle with measure and type.
Acute and made according to Miss Buescher's standards
200
Use figure C. What is angle a, b, c if d is 20. What rules did you use to come to this conclusion?
b is 20 because of vertical rule. a is 160 because of the adjacent rule c is 160 because of the vertical rule.
200
Prove that an quadrilateral angles adds up too 360.
One triangle equals 180, but two triangles equals 360 which makes an quadrilateral
200
Use Figure E. Are these figures congruent? why or why not (use the rule in your explanation)
No because one side does not match its corresponding side.
300
What is a flat surface that has no thickness and extends forever?
Plane
300
What is the different a straight angle and a supplementary angles?
Straight angle is only one angle add up to 180 while supplementary is two angles added up to 180
300
Use Figure B. What is Angle 6? What rule did you use?
60....alternate interior angles
300
What is used to make multiple triangle out of a quadrilateral?
Diagonal
300
How can you tell that two triangles are congruent?
Corresponding sides must be congruent
400
Use Figure A on the board. Name 3 rays.
arrow symbol on top AB, CD, FD..etc
400
Give an example complementary angles?
Two angles that add up to 90...example 45 45
400
Draw a picture of a skew lines.
Answer will vary. Miss Buescher is the judge
400
How many triangles used in an octagon and what is is the total measure?
6 and the 1280
400
How do you tell a square is congruent?
corresponding angles and sides must be congruent. Remember this polygon has more than 3 sides.
500
If two sides of a figure are congruent, what type of marking you will make to show this?
tick mark
500
Angle J and Angle T are complementary. Angle J is 20. What is Angle T?
Angle T is 160
500
What type of lines are intersecting and in the same plane?
Perpendicular
500
How many triangles are in a hexagon? What is the total amount for all angle measures?
4 and then 720
