Scale Factor/Proportions
What is a Scale Factor?
What is the number that determines if a shape grows or shrinks
What does corresponding mean?
What is the same spot
What does congruent mean?
What is equal to?
What is the definition of similarity for triangles?
What is all corresponding angles are congruent and all corresponding sides are proportional.
If you are using scale factor to find a missing side on a BIGGER triangle you will divide
What is false?
What is a Proportion?
What is two ratios set equal to each other?
Triangle ABC is congruent to Triangle XYZ, list the corresponding sides
What is AB/XY, BC/YZ, CA/ZX
How many degrees do the angles in a triangle add up too?
What is 180?
How do you determine if all sides of triangles are proportional?
Proportions are equal to each other
What is True
What is the scale factor of the following:
16/24 = 4/6
What is 4?
Triangle HIJ is congruent to Triangle EFG, Set up a proportion using corresponding sides
What is HI/IJ = EF/FG or any other correct proporiton
What is they have the same markings?
Look at drawing, is this triangle similar?
What is yes
If all angles are congruent it means that all sides are congruent
What is false?
Use the scale factor to find x, what is the scale factor and what is x
15/10 = 6/x
What is 2.5 and 4
AB = 10, BC = 12, AC = 15 and DE= 5, EF = 6, DF = 7.5
are the corresponding sides proportional? If so what is the scale factor
What is yes and 2
If one angle in a triangle is equal to 85 and another angle is equal to 55 how do you find the last angle?
What is that measurement
What is subtract both from 180 and 40?
Look at drawing, are the triangles similar?
What is no
A side of a triangle is represented by two capital letters and a line above them
What is true?
Use the scale factor to find x, what is the scale factor and x:
60/x = 12/15
What is 5 and 75
AB = 75, BC = 65, AC = 55 and HI = 15, IJ = 13, HJ = x
Find what HJ should be. The sides are proportional
What is 11?
There is only one angle marked in both triangles. Can you determine if the angles of the triangles are congruent?
What is no, not enough information?
Look at the drawing, is the triangle similar
What is yes?
What is true?
