Geometry & Trig

Which sides of a right angled triangle create the right angle?

• The hypotenuse and the adjacent

• The hypotenuse and the opposite

• The opposite and the adjacent

• Any of the sides may create a right angle.

• The sine and the cos

When do we use the Cosine Rule?

• When we have 2 sides of a triangle and a subtended angle

• When we have 2 sides of a triangle and an opposite angle

• When we have a right angled triangle

• When we have 3 sides of a triangle

Which of the following combinations could NOT be the sides of a right angled triangle?

• 3,4 and 5

• 5, 12 and 13

• 7, 24 and 25

• 6, 7 and 10

When do you have an "Ambiguous Case" for a triangle's measurements?

• When you have two sides and an angle opposite one of these sides

• When you have two sides and an angle subtended by both of these sides

• When you have two angles and a side opposte one of these angles

• When you have two angles and only one side connecting these angles

How do you calculate the tangent? (Tan A)

• opposite side divided by hypotenuse

• adjacent side divided by hypotenuse

• opposite side divided by adjacent side

• Hypotenuse divided by the opposite side
