    Find the missing angle. - ProProfs

    Find the missing angle.

    • 180

    • 70

    • 25

    • 80

    Correct Answer
    A. 70
    Explanation
    The sum of the angles in a triangle is always 180 degrees. In this case, we are given three angles: 70, 25, and 80. To find the missing angle, we subtract the sum of these angles from 180. 70 + 25 + 80 = 175. Therefore, the missing angle is 180 - 175 = 5 degrees. However, this answer contradicts the given answer of 70, so there may be an error in the question or the given answer.

    Identify the triangle below. - ProProfs

    Identify the triangle below.

    • Obtuse triangle

    • Right triangle

    • Equilateral triangle

    • Acute triangle

    Correct Answer
    A. Obtuse triangle
    Explanation
    The given triangle is an obtuse triangle because it has one angle that measures more than 90 degrees. In an obtuse triangle, one of the angles is greater than 90 degrees, while the other two angles are acute (less than 90 degrees).

    Identify the quadrilateral below. - ProProfs

    Identify the quadrilateral below.

    • Rhombus

    • Parallelogram

    • Trapezoid

    • Rectangle

    Correct Answer
    A. Trapezoid
    Explanation
    The given figure is a trapezoid because it has only one pair of parallel sides. A trapezoid is a quadrilateral with one pair of parallel sides and the other pair of non-parallel sides are not equal in length. In this case, the figure has one pair of parallel sides and the other pair of sides are not equal in length, making it a trapezoid.

    Identify the triangle below. - ProProfs

    Identify the triangle below.

    • Right scalene triangle

    • Right obtuse triangle

    • Equilateral acute triangle

    • Obtuse isosceles triangle

    Correct Answer
    A. Right scalene triangle
    Explanation
    The triangle is identified as a right scalene triangle because it has one right angle (90 degrees) and all three sides are of different lengths.

    • Trapezoid

    • Parallelogram

    • Triangle

    • Rhombus

    Correct Answer
    A. Rhombus
    Explanation
    The given polygon is a rhombus because it has four equal sides and opposite angles are equal. A rhombus is a quadrilateral with all sides of equal length.

    • 115

    • 93

    • 65

    • 70

    Correct Answer
    A. 65
    Explanation
    The measure of angle C is 65.

    Rate this question:

  • 14. 
    What is the measure of angle B? - ProProfs

    What is the measure of angle B?

    • 135

    • 45

    • 90

    • 180

    Correct Answer
    A. 45
    Explanation
    Angle B is measured as 45 degrees because it is a right angle. A right angle is defined as an angle that measures exactly 90 degrees. Therefore, since angle B is not a right angle, it cannot be 90 degrees. Additionally, angles less than 45 degrees would not fit the given options. Therefore, the only logical answer is that angle B measures 45 degrees.
