Legs
What letters do the legs of a triangle go with?
A and B
What letters does the hypotenuse go with?
C
What is it called when you slide a shape
Translation
Triangle ABC has the coordinates (1,3) (3,5) (6,3). If you dilate the triangle by a scale factor of 2. What is the new coordinates? (You need three coordinate pairs to get the correct answer).
(2,6) (6,10) (12,6)
X is at (5,0) after a translation, X' is at (10,0). Z was at (12,13). Where would Z be after the same translation?
Z' = (17,13)
Your legs are 5 in and 7 in. What is the length of the hypotenuse?
8.6
One leg is 12 feet. The hypotenuse is 20 feet. What is the other leg's length?
16 feet
What is it called when you flip a shape?
Reflection
Triangle ABC has the coordinates (1,3) (3,5) (6,3). If you dilate the triangle by a scale factor of 1/2, what are the new coordiantes?
(.5, 1.5) (1.5, 2.5) (3, 1.5)
10.8
A ladder is 9 feet long and is slanted up against a wall. It is 5 feet away from the wall. How high up the wall is it slanted? (Reminder for Mr C to draw a picture)
7.48 or 7.5 feet
What is it called when you spin a shape?
Rotation
Triangle ABC has the coordinates (1,3) (3,5) (6,3). If you dilate the triangle by a scale factor of 14, what are the new coordinates
Legs are 3 meters and 5 meters? What is the hypotenuse?
5.8 meters
One leg is 6 inches. The other is unknown. The hypotenuse is 13 inches.
11.5 inches
What is it called when you make a shape bigger or smaller?
Dilation
Your original points were at (14, 16) and (0, 9). After a dilation, they were at (21, 24) and (0, 13.5). What was the scale factor?
1.5
The legs are 12 feet and 16 feet. What is the hypotenuse?
20 feet
Is this a right triangle? How do you know?
Legs: 14 feet and 21 feet
Hypotenuse: 15 feet
The hypotenuse is always the longest side. So without doing any math, I know this is not a right triangle.
If Point A is at (0,3) and you dilate by a scale factore of 4. What is your new point?
(0,12)
Your original points were at (2,2) (3,3) (4,4) (5,7). After a dilation, the new points are at (12,12) (18,18) (24,24) and (30,42). What was the scale factor?
6
