Indicate the correct answer by = clicking=20 on the button next to the letters A, B, C or D. There is only one = correct=20 answer per question. After you have answered all = multiple=20 choice questions compare your choices with the correct answers.=20

Geometry - Trigonometry

The questions are based on the figure below:=20

3Dtriangle=20=20

1.) The area of the triangle is given by ...=20
    A   A =3D =C2=BD (a+b)c
    B   A =3D =C2=BD a =C2=B7 b
    C   A =3D =C2=BD a =C2=B7 c
    D   A =3D a2 + b2 -=20 c2
2.) Which expression is wrong:=20
    A   c2 =3D a2 + = b2
    B   c2 - a2 =3D = b2
    C   b2 - c2 =3D = a2
    D   b2 - a2 + 2a2 = =3D=20 c2
3.) Which expression regarding the values of the angles = is=20 right:=20
    A   =CE=B1 + =CE=B2 < 90o
    B   =CE=B1 + =CE=B2 > 90o
    C   180o + (=CE=B1 + =CE=B2) =3D = 360o
    D   180o - =CE=B1 =3D 90o +=20 =CE=B2
4.) If the length of side c is 13 cm, the length of side = a is 5=20 cm, what will be the length of side b?=20
    A   7 cm
    B   8 cm
    C   12 cm
    D   18 cm
5.) Which expression is correct?=20
    A   sin =CE=B2 =3D c/b
    B   sin =CE=B2 =3D b/a
    C   sin =CE=B1 =3D b/c
    D   sin =CE=B1 =3D a/c
6.) Spot the mistake:=20
    A   sin =CE=B2 =3D b/a
    B   sin =CE=B1 =3D a/c
    C   cos =CE=B2 =3D a/c
    D   cos =CE=B1 =3D b/c
7.) Identify the wrong expression:=20
    A   a =3D c =C2=B7 sin =CE=B1
    B   a =3D c =C2=B7 cos =CE=B1
    C   b =3D c =C2=B7 sin =CE=B2
    D   a =3D c =C2=B7 cos =CE=B2 =
8.) The tan of angle =CE=B2 is given by ...=20
    A   tan =CE=B2 =3D b/a
    B   tan =CE=B2 =3D a/b
    C   tan =CE=B2 =3D b/c
    D   tan =CE=B2 =3D a/c
9.) The sin of 30o is ...=20
    A   1
    B   2/3
    C   1/2
    D   1/4
10.) The cos of 60o is the same as ...=20
    A   tan 45o
    B   tan 60o
    C   sin 30o
    D   sin 60o
