About This Quiz

Quiz 1 (Year 6) May 2020 assesses mathematical skills, focusing on geometry. Students solve for unknowns in angles and numbers, enhancing their problem-solving abilities and preparing for advanced math concepts.

Questions and Answers

2.

Find the angle x
3.

If angle b is 124, Find angle a

Explanation
Since the question states that angle b is 124, and the answer given is 56, it can be inferred that angle a is the complement of angle b. In other words, angle a and angle b add up to 180 degrees. Therefore, if angle b is 124, angle a must be 180 - 124 = 56 degrees.

Name this triangle
- Scalene triangle
- Isosceles Triangle
- Equilateral Triangle
- Right-Angle Triangle
Correct Answer

A. Equilateral Triangle

Explanation

An equilateral triangle is a type of triangle where all three sides are equal in length. This means that the angles opposite each side are also equal, measuring 60 degrees each. In contrast, a scalene triangle has no equal sides or angles, an isosceles triangle has two equal sides and angles, and a right-angle triangle has one angle measuring 90 degrees. Since the given triangle is not described as having any specific angles or side lengths, but is simply named, it can be inferred that it is an equilateral triangle.

Name this triangle.
- Acute Triangle
- Right-angle triangle
- Obtuse triangle
- Equilateral triangle
Correct Answer

A. Obtuse triangle

Explanation

An obtuse triangle is a type of triangle that has one angle greater than 90 degrees. In this triangle, one of the angles is greater than 90 degrees, making it an obtuse triangle.

Angle sum for all types of the triangle is NOT equal to 180⁰
- True
- False
Correct Answer

A. False

Explanation

The statement "Angle sum for all types of the triangle is NOT equal to 1800" is false. The angle sum of any triangle is always equal to 180 degrees. This is a fundamental property of triangles in Euclidean geometry. Regardless of the type of triangle (equilateral, isosceles, scalene), the sum of its interior angles will always be 180 degrees. Therefore, the correct answer is false.
