    What is the name for a triangle that has a 90 degree angle?

    • Acute Triangle

    • Obtuse Triangle

    • Right Triangle

    • Isosceles Triangle

    Correct Answer
    A. Right Triangle
    Explanation
    A triangle that has a 90 degree angle is called a right triangle. In a right triangle, one of the angles is a right angle, which measures 90 degrees. This means that one of the sides of the triangle is perpendicular to the other two sides.

    What makes a triangle Isosceles?

    • All three sides are the same length

    • Two of the sides are the same length

    • None of the sides are the same length

    • Four sides are the are the same length

    Correct Answer
    A. Two of the sides are the same length
    Explanation
    An isosceles triangle is defined as a triangle that has two sides of equal length. Therefore, the correct answer is "Two of the sides are the same length." This is because in an isosceles triangle, the third side may or may not be of the same length as the other two sides.

  • 4. 

    How many degrees do the three angles of a triangle add up to?

    • 90

    • 180

    • 200

    • 360

    Correct Answer
    A. 180
    Explanation
    The three angles of a triangle always add up to 180 degrees. This is a fundamental property of triangles in Euclidean geometry. It can be proven using the fact that the sum of the angles in any polygon is equal to (n-2) * 180 degrees, where n is the number of sides of the polygon. Since a triangle has three sides, the sum of its angles is (3-2) * 180 = 180 degrees.

  • 5. 

    If the sides of a triangle are 8 ft, 4 ft, and 5 ft what type of triangle is it?

    • Scalene

    • Isosceles

    • Equilateral

    • Quadrilateral

    Correct Answer
    A. Scalene
    Explanation
    A scalene triangle is a triangle in which all three sides have different lengths. In this case, the given triangle has sides measuring 8 ft, 4 ft, and 5 ft, which are all different lengths. Therefore, it can be classified as a scalene triangle.

    Rate this question:

  • 6. 

    If two of the angles in a triangle are 50 degrees and 100 degrees what is the third angle?

    • 10 degrees

    • 50 degrees

    • 90 degrees

    • 30 degrees

    Correct Answer
    A. 30 degrees
    Explanation
    The sum of the angles in a triangle is always 180 degrees. If two of the angles are 50 degrees and 100 degrees, the sum of these two angles is 150 degrees. To find the third angle, we subtract the sum of the two known angles from 180 degrees. Therefore, the third angle is 180 - 150 = 30 degrees.

    Rate this question:

  • 7. 

    If the three angles of a triangle measure 60, 80, and 40 degrees what type of triangle is it?

    • Acute

    • Obtuse

    • Right

    • Straight

    Correct Answer
    A. Acute
    Explanation
    The three angles of a triangle measure 60, 80, and 40 degrees. In a triangle, the sum of all angles is always 180 degrees. Since the sum of these three angles is less than 180 degrees (60 + 80 + 40 = 180), the triangle is an acute triangle.

    What type of triangle is shown below? - ProProfs

    What type of triangle is shown below?

    • Equilateral, Right

    • Isosceles, Obtuse

    • Isosceles, Right

    • Equilateral, Acute

    Correct Answer
    A. Equilateral, Acute
    Explanation
    The given triangle is an equilateral triangle because all three sides are equal in length. Additionally, the triangle is acute because all three angles are less than 90 degrees.

    How would you name this triangle by its sides? - ProProfs

    How would you name this triangle by its sides?

    • Scalene

    • Isosceles

    • Equilateral

    • Acute

    Correct Answer
    A. Isosceles
    Explanation
    An isosceles triangle is a triangle that has two sides of equal length. In this case, since the question does not provide any information about the lengths of the sides, we can assume that two of the sides are equal. Therefore, the correct answer is "Isosceles."

    How would you name this triangle by its angles? - ProProfs

    How would you name this triangle by its angles?

    • Scalene

    • Right

    • Obtuse

    • Acute

    Correct Answer
    A. Obtuse
    Explanation
    This triangle would be named "Obtuse" based on its angles. An obtuse triangle is a triangle that has one angle greater than 90 degrees. Since the question does not provide any information about the angles of the triangle, we can assume that it has at least one angle greater than 90 degrees, making it an obtuse triangle.
