Angles of a Triangle
Classify a Triangle
2nd triangle inequality
Isosceles Triangles
Midsegments
100
The missing angle measure:
71 degrees
100
Give the complete classification of the triangle:
Isosceles acute
100
List the angles from smallest to largest:
Smallest: Angle B
medium: Angle A
Largest: Angle C
100
The value of x:
x = 55

If DE is a midsegment and has the equation y = 1/7 x + 4 , what is the slope of BC? Explain.
The slope of BC = 1/7 because midsegments are parallel and parallel lines have the same slope.

The value of x
x = 24

The complete classification of the triangle:
Scalene obtuse

List the sides of triangle DEG from shortest to longest.
Shortest: GE
Middle: DE
Longest: DG
200
The value of x:
x = 22
200
If AB is a midsegment, the value of x:
x = 6
300
The measure of angle K
73 degrees
300
The complete classification:
Its a trick question:
the side lengths do not actually make a triangle:
4 + 11 = 15
and 15 is not greater than 17
300
The error in the picture below:
The biggest side is not across from the biggest angle
(or the medium side is not across from the medium angle)
300
The value of x:
x = 19/2 or x = 57/6 or x = 9.5
300
If DE is a midsegment, the value of x:
x = 2
