Angles
Will the angles: 47 degrees, 53 degrees, & 80 degrees create a triangle?
47+53+80=180 YES, this will create a triangle
Will the sides: 8ft, 12ft, & 15ft create a triangle?
Rewrite in Increasing order
8, 12, 15
8+12> 15
20 > 15
YES it will form a triangle
What is the name of a triangle that has "the box"
A triangle has angles: <A=45 degrees, <B=45 degrees what is the measurement of <C=?
"The box" in the right triangle is how many degrees?
90 degrees
Will the Angles: 35 degrees, 40 degrees, and 65 degrees make a triangle?
35 + 40 + 65= 140 NO will not make a triangle
Will the sides: 3ft, 7ft, & 4ft create a triangle?
Rewrite in increasing order
3, 4, 7
3+4>7
7 > 7
NO it wont create a triangle
What is the name of a triangle that has LESS than 90 degrees and 2 equal sides?
Acute Isosceles Triangle

Measurement of <C= 80 degrees
How many sides are equal in an isosceles triangle?
2 equal sides
Will the Angles: 46 degrees, 54 degrees, & 80 degrees make a triangle?
46 + 54 + 80 = 180 YES these degrees in the angles will create a triangle
Will the sides: 21ft, 1ft, & 20ft create a triangle?
Rewrite in increasing order
1, 20, 21
1 + 20 > 21
21>21
NO it wont
