Right angle = Is a 90° degrees angle

Obtuse angle= is more than 90° but less than 180°

Acute angle=less than 90°

So:

Angle CGE starts at 70° (C.top row) and ends at E 160°.

To find the measure:

160-70 = 90°

SO,

Angle BGD:

B =20°

D≅ 113° (picture isn't clear enough)

BGD = 113-20 =93

Obtuse angle (more than 90°)

Angle CGB

C = 70°

B =20°

CGB = 70-20 = 50°

Acute angle (less than 90°)
