May someone please help me?
Look at the figure shown below.

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°.
