True or False:
These sides lengths can form a triangle
Side 1: 1 cm
Side 2: 5 cm
Side 3: 12 cm
What is False?

True or False:
These sides lengths can form a triangle
Side 1: 4 cm
Side 2: 5 cm
Side 3: 7 cm
What is True?
The two smallest sides must be greater than the biggest side
4+5 = 9, 9 is greater than 7
300
The value of x
What is 10 degrees?
The angles have are congruent (have the same measure).
Write an equation: 5x+3 = 53
300
True or False:
These angles can form a triangle
Angle 1: 30

300
True or False:
These sides lengths can form a triangle
Side 1: 10 cm
Side 2: 8 cm
Side 3: 15 cm
What is true?
The two smallest sides must be greater than the biggest side
10+8 = 18, 18 is greater than 15
300
On a floor plan, the scale is 1 inch = 2 feet.
What is the actual length of the room if floor plan shows that the room is 5 inches?

400
On a map, the scale is 1 inch = 40 miles.
Find the actual distance between two cities if the map distance is 6 inches
What is 240 miles?
The scale factor is 40, so you multiply 6 by 40
500

500
True or False:
These sides lengths can form a triangle
Side 1: 52 cm
Side 2: 13 cm
Side 3: 74 cm
What is true?
The two smallest sides must be greater than the biggest side
52+13 = 75, 75 is greater than 74
500
On a scale drawing, the scale is 1/2 inch = 1 foot.
Find the dimensions on the scale drawing for a room that is 10 feet by 15 feet
What is 5 inches by 7.5 inches?
The scale factor is 1/2, so you multiply both numbers by 1/2
