  • Q3
    3. What is the Pythagorean Theorem?
    The sum of all angles in a triangle is 180 degrees.
    The longest side of a triangle is called the hypotenuse.
    The area of a triangle is equal to half the product of its base and height.
    In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
    The ratio of the lengths of the sides in a right triangle is always the same.

    4. What is the relationship between the lengths of the sides in an equilateral triangle?
    The lengths of the sides can vary.
    All sides are equal
    The length of one side is twice the length of the other two sides.
    The shortest side is equal to the difference between the other two sides.
    The longest side is equal to the sum of the other two sides.

  • Q8
    8. What is the relationship between the angles in a right triangle?
    One angle is always 90 degrees
    All angles are acute angles
    The sum of angles is always greater than 90 degrees
    The angles can vary
    All angles are obtuse angles

  • Q9
    9. What is the longest side of a right triangle called?
    Adjacent side
    Base
    Opposite side
    Height
    Hypotenuse

  • Q10
    10. What is the formula to calculate the area of a triangle?
    Area = (base * height) * 2
    Area = (base + height) / 2
    Area = base * height
    Area = (base * height) / 2
