Question

Look at the figure shown below.




Sonja determines that triangle CGD is an isosceles triangle.

Which statement best describes Sonja’s conclusion?

It is incorrect because angle GCD = 42°, angle GDC = 36°, and angle CGD = 102°.

It is incorrect because angle GCD = 48°, angle GDC = 36°, and angle CGD = 96°.

It is correct because angle GCD = 42°, angle GDC = 42°, and angle CGD = 96°.

It is correct because angle GCD = 48°, angle GDC = 48°, and angle CGD = 84°.

Answer 1

It is correct because angle GCD = 42°, angle GDC = 42°, and angle CGD = 96°. A isoceles triangles has two equal angles and every triangle has a total of 180 degrees

Answer 2
