Jeff determines that triangle CGD is an isosceles triangle. Which statement best describes Jeff’s conclusion? It is incorrect because angle GCD = 54°, angle GDC = 36°, and angle CGD = 90°. It is correct because angle GCD = 54°, angle GDC = 63°, and angle CGD = 63°. It is correct because angle GCD = 36°, angle GDC = 72°, and angle CGD = 72°. It is incorrect because angle GCD = 36°, angle GDC = 81°, and angle CGD = 63°.
i am pretty lost on this problem i need help. . . can someone help me please?
i dont understand how the numbers of degrees is in the same triangle in each choice
you familiar with- vertically opposite angles ? can you tell what angle G is ?
no i am not...
oh thats makes it a lil bit easier
knocked out 2 of the options now a 50/50
which two you think ?
B and C
yeah thats right!
so its B sweet B-)
cuz what gives it away is the 63 degree right?
|dw:1343366827481:dw|
that is vertcally opposite
right?
correct ! so it equals what ?
i mean in your pix- angle G equals what ?
63?
thats right!!
yay!!!!! B-)
you can find C, the same way using triangle ABC
yeah i can see that. . . i call that a bonus lol
once you have C, you have D as well... then its easy to figure out :)
sweet B-) thanks for your help i deeply appreciate it B-)
np... yw:D
