Answer 1

Prove that the sum of the measures of the interior angles of a triangle is 180°. Be sure to create and name the appropriate geometric figures.

Answer 2

help? please.

Answer 3

draw a line // AB from C
draw a line // AC from B
the intersection of those lines is D

Answer 4

we have C1+C2+C3 =180 (straight line)

Answer 5

Use parallel line properties, we get C2 = B
C3 =A
hence A +B +C1 =180

Answer 6

DAT SIT

Answer 7

if it looks like I am not viewing the question know that I am my computer is messed up

Answer 8

so what would I put if I wanted to write this as a paragraph? (it doesnt have to be a long one.)

Answer 9

why paragraph? all you need is the proof and I gave you all.

Answer 10

oh so I would write c2=b and c3=a then a+b+c1=180...?

Answer 11

Prove that opposite angles of a parallelogram are congruent. Be sure to create and name the appropriate geometric figures.
