Right Triangle - Sine

Looking at Triangle ABC where Angle B is a right angle,

What would happen to the angles if we doubled each side length?

• The angles will double
• The angles will become acute angles
• The angles will become obtuse angles
• The angles will remain the same.

Which Trig function do you use?

• Sine
• Cosine
• Tangent

Which is the ratio of the opposite leg to the hypotenuse in a right triangle?

• sine
• cosine
• tangent
• secant

 Find sinA

• 32/40
• 32/24
• 24/40
• 24/32

What is the correct ratio?

• sin 40 = w/28
• cos 40 = w/28
• tan 40 = w/28
• sin 40 = 28/w
