Coterminial and supplementary and complimentary angle in radians described

The video tutorial covers transformations in trigonometry, focusing on complementary, supplementary, and coterminal angles. It explains how to calculate these angles using radians, emphasizing the importance of understanding fractions and denominators in these calculations. The tutorial also highlights common mistakes students make and provides strategies to avoid them.

What is the radian measure for complementary angles in trigonometry?

• π/3

• 2π

• π/2

• π

How do you find a supplementary angle if one angle is given?

• Add the angle to π

• Subtract the angle from π

• Multiply the angle by π

• Divide the angle by π

What is the radian measure for supplementary angles?

• π/2

• π

• 3π/2

• 2π

How can you determine coterminal angles?

• Add or subtract multiples of π/3

• Add or subtract multiples of 2π

• Add or subtract multiples of π

• Add or subtract multiples of π/2

What is the result of adding 2π to an angle?

• It becomes a complementary angle

• It becomes a supplementary angle

• It becomes a negative angle

• It becomes a coterminal angle

If an angle is given as 5π/6, what is the process to find its coterminal angle?

• Add 2π

• Subtract π

• Subtract 2π

• Add π

What should you do if the calculated angle is negative when finding complementary angles?

• Recalculate using a different method

• Convert it to a positive angle

• Ignore the negative angle

• Use the negative angle
