1. In a right-angled triangle, what is the side opposite the 90-degree right angle called?Adjacent sideCathetusHypotenuseOpposite side
2. In a right triangle, how is the Sine (sin) of an acute angle defined?Adjacent side / HypotenuseHypotenuse / Opposite sideOpposite side / Adjacent sideOpposite side / Hypotenuse
3. Can the value of sin(θ) or cos(θ) for an acute angle in a real triangle ever exceed 1?No, the hypotenuse is the longest sideNo, unless measured in radiansYes, for angles over 45 degYes, when sides are very large
