Define a Transformation and the 3 examples
A movement of a shape
- Translation
- Rotation
- Reflection
100
What type of transformation is this? Give details of the transformation
Translation
Up 3, left 6
100
Define parallel
Lines that are the same that will NEVER intersect
100
Define congruent
Same shape
100
What are alternate interior angles?
a pair of angles on the inner side of two lines, but on opposite sides of a crossing line called a transversal.
100
Define Acute angle, Obtuse angle, and Right angle
- Less than 90 degrees
- More than 90 degrees
- 90 degrees
100
What do all angles in a triangle add up to?
180 degrees
100
Tell me which two different types of angles that cannot be in the same triangle
Right and obtuse
200
Define a Translation and the two things you need to describe a translation
A shift of a figure
- Direction
- Distance
200
What type of transformation is this? Give details of the transformation
Rotation
Answer can vary- 90 degrees around origin
200
Define a Transversal
A line that intersects two or more other lines at different points
200
Are these congruent? Why or why not?
No! They are not the same exact shape!
200
Find the missing angle
x- 110
200
Define corresponding
Same point/line/angle on the original and new image
200
Find the missing angle
60 degrees
200
Can congruent shapes have different angles? Or just different sides? (Hint: think area and perimeter example)
They have to have the same of both
300
Explain the three main things you need to describe a rotation
Center of rotation, direction, degrees
300
Find the center of rotation of this picture (DAILY DOUBLE)
(1, 2)
300
Given that the following lines are parallel, find the missing angle measurement of DBC and EFB
DBC: 36 degrees
EFB: 144 degrees
300
Are these considered congruent? What do the small lines on the sides represent?
Yes, they mean that they are the same side/congruent
300
Find angles b, d, and h
b- 110
d- 70
h- 70
300
Give a explanation on alternate interior angles.
Angles that are across/alternate from one another that are congruent. Can be the same on the lines connected to the transversal ONLY if they are parallel.
300
Find the measurement of x
158 degrees
300
Name the shapes that are always congruent:
- Squares - Quadrilaterals
- Rectangles - Parallelograms
- Rhombus
Squares and Rectangles
400
Define a rigid transformation and why they are important to what we have been doing
A movement of a shape that does not change the actual shape itself, just the position!
It is the translations, reflections, and rotations we have been doing!
400
How would you get the image B back to the original A?
Translate up 4, left 5
400
Find the missing angles AEH and DFG, given the following lines are parallel
AEH: 118
DFG: 118
400
Do area and perimeter have to be the same when shapes are congruent? Why or why not?
Yes, if they are not, then it is not the same shape
400
Find the angle x and tell me how you did so
97, obtuse angle, and alternate interior to the corresponding angle of 97 degrees
400
Tell me all 6 types of directions used for translation and rotation. (DAILY DOUBLE)
Up, down, left, right, clockwise, counterclockwise
400
Find the 4 missing angles
inside triangle: 54
a: 119
b: 126
c: 115
400
Describe what the line y=x looks like on a graph
(DAILY DOUBLE)
500
Define a vertex and describe what it is mainly used for in a specific type of transformation
A point where lines meet, Center of rotation!
500
Describe a sequence of transformations that would take HJKL to H'J'K'L'.
Rotate 90 degrees clockwise around the origin, reflect across the x-axis, translate 1 unit down and 3 units right
500
Tell me each pair of alternate interior angles
1-3, 5-7
2-4, 6-8
500
Which of the following is the ONLY one considered always congruent with the same side lengths? Explain why
- Rectangle
- Rhombus
- Quadrilaterals
Rectangle- if side lengths are the same, they are always congruent because angles and sides are the same
500
Find the missing angle x (DAILY DOUBLE)
x-45
500
Define image
The shape after a transformation was done (end result)
500
Find the value of y
140 degrees
500
What does it mean when two angles add up to 180 degrees? What are those angles called?
