    The angle sum of any triangle is _______________ degrees.

    Explanation
    The angle sum of any triangle is always 180 degrees. This is a fundamental property of triangles in Euclidean geometry. The sum of the interior angles of a triangle is always equal to 180 degrees, regardless of the size or shape of the triangle. This property can be proven using various geometric theorems and principles.

    The angle sum of any quadrilateral is _______________ degrees.

    Explanation
    The angle sum of any quadrilateral is always 360 degrees. This is because a quadrilateral has four sides, and the sum of the interior angles of any polygon is given by the formula (n-2) * 180 degrees, where n is the number of sides. Therefore, for a quadrilateral with four sides, the sum of the interior angles is (4-2) * 180 = 360 degrees.

    A ______________________ polygon is a polygon in which all sides are the same length and all angles are the same measure.

    Explanation
    A regular polygon is a polygon in which all sides are the same length and all angles are the same measure. This means that all the sides of the polygon have equal lengths and all the angles of the polygon have equal measures. In other words, a regular polygon is a symmetrical shape with uniform sides and angles.

    • An angle that is more than 90 degrees

    • An angle that is equal to 90 degrees

    • An angle that is less than 90 degrees

    • None of these

    Correct Answer
    A. An angle that is less than 90 degrees
    Explanation
    An acute angle is defined as an angle that measures less than 90 degrees. This means that the angle is smaller than a right angle, which measures exactly 90 degrees. Therefore, the correct answer is "An angle that is less than 90 degrees."

    Rate this question:

  • 10. 

    What is an obtuse angle?

    • An angle that is more than 90 degrees

    • An angle that is equal to 90 degrees

    • An angle that is less than 90 degrees

    • None of these

    Correct Answer
    A. An angle that is more than 90 degrees
    Explanation
    An obtuse angle is defined as an angle that is greater than 90 degrees. In other words, it is an angle that is wider or "more open" than a right angle, which measures exactly 90 degrees. An obtuse angle can range from slightly greater than 90 degrees to almost 180 degrees, but it cannot be equal to or less than 90 degrees. Therefore, the correct answer is "An angle that is more than 90 degrees."

    What is another name for a 90 degree angle?

    • An obtuse angle

    • An acute angle

    • A straight angle

    • A right angle

    Correct Answer
    A. A right angle
    Explanation
    A right angle is another name for a 90 degree angle. In geometry, a right angle is formed when two lines or line segments intersect at a 90 degree angle, creating a square corner. It is called a right angle because it is the "correct" or "right" angle in terms of its measure.

    A shapre that looks the same when it is rotated less than a full turn has ___________________________________.

    • Rotation symmetry

    • Reflection symmetry

    Correct Answer
    A. Rotation symmetry
    Explanation
    A shape that looks the same when it is rotated less than a full turn has rotation symmetry. This means that the shape can be rotated by a certain angle (less than 360 degrees) and still maintain its original appearance. The presence of rotation symmetry indicates that the shape has a balanced and harmonious design, allowing it to be visually appealing from different angles of rotation.

    • A

    • B

    • C

    • D

    Correct Answer
    A. D
    Explanation
    Figure D is a polygon because it is a closed shape with straight sides. A polygon is a 2-dimensional shape that has straight sides and angles, and the sides of a polygon do not intersect. Figure D meets these criteria as it is a closed shape with straight sides and angles, making it a polygon.

    In the diagram, Line L1 is parallel to Line L2.  What is the measure of angle 3? - ProProfs

    In the diagram, Line L1 is parallel to Line L2.  What is the measure of angle 3?

    • 110 degrees

    • 70 degrees

    • 180 degrees

    • 20 degrees

    Correct Answer
    A. 110 degrees
    Explanation
    In the diagram, Line L1 is parallel to Line L2, which means that angle 3 is an alternate interior angle with angle 1. Alternate interior angles are congruent when the lines are parallel. Since angle 1 measures 110 degrees, angle 3 also measures 110 degrees.

  • 17. 
    What is the measure of the angle labeled x? - ProProfs

    What is the measure of the angle labeled x?

    • 65 degrees

    • 90 degrees

    • 180 degrees

    • 75 degrees

    Correct Answer
    A. 75 degrees
    Explanation
    The measure of the angle labeled x is 75 degrees. This can be determined by observing that the angle is not a right angle (90 degrees) or a straight angle (180 degrees). It is also not stated that the angle is supplementary to any other angle, so it cannot be determined to be 180 degrees. Therefore, the only remaining option is 75 degrees.

    Polygon A is a square.  Polygon B has four more sides than Polygon A.  What type of polygon is Polygon B?

    • Octagon

    • Hexagon

    • Decagon

    • Pentagon

    Correct Answer
    A. Octagon
    Explanation
    Polygon A is a square, which means it has four sides. The question states that Polygon B has four more sides than Polygon A. Since Polygon A has four sides, Polygon B must have four more sides than that, making it an octagon.

    In the diagram, Line L1 is parallel to Line L2.  What is the measure of angle 1? - ProProfs

    In the diagram, Line L1 is parallel to Line L2.  What is the measure of angle 1?

    • 110 degrees

    • 70 degrees

    • 180 degrees

    • 20 degrees

    Correct Answer
    A. 110 degrees
    Explanation
    Since Line L1 is parallel to Line L2, angle 1 is a corresponding angle to the angle formed by the intersection of Line L1 and Line L2. Corresponding angles are congruent when two parallel lines are intersected by a transversal. Therefore, the measure of angle 1 is 110 degrees.

    Which is the correct formula for finding the angle sum of any polygon?

    • (# of sides - 1) x 180 = angle sum

    • (# of sides - 2) x 360 = angle sum

    • (# of sides - 2) x 180 = angle sum

    • (# of sides + 2) -180 = angle sum

    Correct Answer
    A. (# of sides - 2) x 180 = angle sum
    Explanation
    The correct formula for finding the angle sum of any polygon is (# of sides - 2) x 180 = angle sum. This formula is derived from the fact that the sum of the interior angles of a polygon is equal to (n-2) times 180 degrees, where n is the number of sides of the polygon. By subtracting 2 from the number of sides and multiplying by 180, we can find the total angle sum of the polygon.
