Labeling Triangle Sides in Right Triangle Trigonometry

What theorem is used to identify similar triangles?

• Pythagorean theorem

• Angle-angle similarity theorem

• Sine rule

• Cosine rule

What defines similar shapes informally?

• Different shapes but same size

• Same size and shape

• Different shapes and sizes

• Same shape, not necessarily the same size

How do you find a missing angle in a triangle?

• Multiply the known angles

• Subtract the known angles from 180

• Add the known angles and subtract from 180

• Divide 180 by the number of angles

Which side is always opposite the right angle in a right triangle?

• Adjacent side

• Opposite side

• None of the above

• Hypotenuse

What is the first step in labeling sides for right triangle trigonometry?

• Identify the right angle

• Label the hypotenuse

• Identify the longest side

• Circle the reference angle

Which side is labeled 'A' in right triangle trigonometry?

• Opposite side

• Adjacent side

• None of the above

• Hypotenuse

What changes when the reference angle is switched in a triangle?

• The hypotenuse

• The opposite and adjacent sides

• The size of the triangle

• The type of triangle

Why is it important to label all sides of the triangle in homework problems?

• To practice drawing

• To find the right angle

• To ensure correct identification of sides

• To make the triangle look complete

What should you do if the problem only asks for the hypotenuse?

• Skip labeling the sides

• Guess the sides based on the triangle's shape

• Label all three sides correctly

• Label only the hypotenuse

What is a common mistake students make when labeling triangles?

• Choosing sides without labeling

• Labeling the sides in alphabetical order

• Labeling all sides as hypotenuse

• Forgetting to label the right angle
