Working with the Isosceles Triangle

Hi, kids. This e-tivity is about using what we have learned about the isosceles triangle to solve problems. By the end, you will be able to
  • find out the measure of a missing interior angle
  • develop a method to solve problems involving triangles

    1. angle b measure 62 degrees
    180-62= 118
    118/2= 59
    59+59+62=180 degrees
    angle a and b measure 59 degrees

    180-50=130
    130/2=65
    65+65+50=180

    angle b measures 62 degees
    180-62=118
    118/2=59
    so angle a & b measure the same (59 decrees)

    1. angle c measure 58°,what would be the
    measures of angles a and b?
    ANSWER:
    180°-58°=122°
    122°/2=61°
    angles a and b measures 61°

    1. Angle C masures 40º. What is the measure of angle A and B?
    2. 180º-40º=140º A+B=140º
    140/2=70 A=70º B=70º
    40º+70º+70º=180º

    angle A measures 42 degrees
    180-42=138
    138/2=69
    69 PLAS 69 PLAS 42=180!!!!

    1. angle b measure 65 degrees equal than angle a
    50 + 65 +65:180 degrees
    i now because any triangle have to measure 180 degrees

    ISOCELES TRIANGLE: If angle C measure 46º, what would be the measure of angles A and B?
    180-46 = 134
    134/2 = 67
    67º + 67º + 46º = 180º

    the intrior angles measure 180 and angle c measure 50. 180 - 50= 130. 130/2=65 and the answer is 65+65+50=180!!!

    180 - 60 =120/2=60

    60 mas 60 mas 60 =180

    1)If angle c measures 44°,so what is the measure of angle a and b?
    2)180°-44°=136°
    136°/2=68°, so angles a and b measures 68°

    hello miss alethia
    angle b measure 62 so
    180-62:118 so the result you sivide by 2
    118/2:59 so angle a b measure the same they measure 59

    1. Angle C Measures 50°
    2. Angles A and C are congruent.
    3. You have to find the measures of angles A and B.
    Answer:
    Angle A: 50 (Because is the same that angle C )
    Angle B: 50 + 50 = 100. 180 - 100 = 80°

    Angle A measures 30°.
    B and C are congruent.
    What is the measures of angles B and C?
    Answer:
    180 - 30 = 150 150/2 = 75
    So angles B and C measure 75°

    Hi miss the answer is:
    Angle B measures=62 degrees
    180-62=118
    118/2=59
    59+59+62=180 degrees
    so, Angle A and angle B measure the same (59 degrees).
