Identifying Parts of Right Triangles

From ∠G, what side is OG?

• Adjacent

• Hypotenuse

• Opposite

Find the missing side

• 48

• 108

• 83.6

• 72

If you are given the opposite side and hypotenuse, which trig function should you use?

• sine

• cosine

• tangent

• cotangent

If you are given the two sides that are not the hypotenuse, which trig function should you use?

• sine

• cosine

• tangent

• cotangent

• 24/32
• 32/24
• 32/40
• 24/40

• 14/48
• 48/50
• 14/50
• 48/14

• 27/36
• 27/45
• 45/36
• 45/27

Choose the correct ratio.

• cos(33)=x/14

• sin(33)=x/14

• cos(33)=14/x

Find the length of the missing side. 

• 17 cm

• 22 cm

• 15 cm

• 13 cm

Choose the correct ratio.

• sinZ=5/13
