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

200

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
