Understanding Right Triangles with Trigonometry

What does solving a right triangle involve?

• Determining all missing sides and angles

• Calculating the area of the triangle

• Identifying if it's a special right triangle

• Finding only the hypotenuse

Which trigonometric function is used for opposite over adjacent sides?

• Cotangent

• Cosine

• Sine

• Tangent

What is the mnemonic device to remember trigonometric functions?

• ROYGBIV

• PEMDAS

• SOH-CAH-TOA

• DNA-RNA

How do you isolate variable 'a' when solving with tangent?

• Subtract 34 from both sides

• Multiply both sides by 8

• Divide both sides by 34

• Add 8 to both sides

How do you adjust your calculator to solve for 'a' using tangent?

• Set to radian mode

• Use the inverse function

• Multiply by π/180

• Set to degree mode

What is the correct equation for finding side 'c' using cosine?

• cos(34) = 8/c

• cos(34) = c/8

• cos(34) = 8*cos(34)

• cos(34) = c*cos(34)

Which theorem is used as an alternative to find the hypotenuse?

• Euler's Theorem

• Pythagorean Theorem

• Fermat's Last Theorem

• Binomial Theorem

What is the sum of all angles in a triangle?

• 270 degrees

• 360 degrees

• 180 degrees

• 90 degrees

What should you do if given a triangle oriented differently?

• Assume it's a special right triangle

• Rotate the triangle

• Only use Pythagorean theorem

• Identify sides relative to a chosen angle

What is the final step in solving a right triangle?

• Calculating the perimeter

• Finding the area

• Labeling all sides and angles

• Determining if it's a scalene triangle
