Section A · multiple choice

  1. 1.

    A right-angled triangle has legs 36 cm and 15 cm. Its hypotenuse is:

    1. 40 cm
    2. 51 cm
    3. 21 cm
    4. 39 cm
    Answer

    (d) 39 cm

    36² + 15² = 1521 = 39²

  2. 2.

    A right-angled triangle has hypotenuse 65 cm and one leg 56 cm. The other leg is:

    1. 9 cm
    2. 121 cm
    3. 33 cm
    4. 34 cm
    Answer

    (c) 33 cm

    65² − 56² = 1089 = 33²

  3. 3.

    In a right-angled triangle, the square on the hypotenuse equals:

    1. twice the other sides
    2. the difference of the other two squares
    3. the product of the other two sides
    4. the sum of the squares on the other two sides
    Answer

    (d) the sum of the squares on the other two sides

Section B · short answer

  1. 4.

    Find the hypotenuse of a right-angled triangle whose legs are 28 cm and 45 cm.

    Answer

    53 cm

    √(784 + 2025) = √2809 = 53

  2. 5.

    A right-angled triangle has hypotenuse 25 m and one leg 7 m. Find the other leg.

    Answer

    24 m

    √(625 − 49) = √576 = 24

Section C · long answer

  1. 6.

    Vikram leans a 29 m ladder against a wall so that it reaches 21 m up. How far from the wall is its foot? If the foot is moved closer so the ladder reaches higher, which length stays the same?

    Answer

    20 m; the ladder's length (29 m)

    √(841 − 441) = 20
