سؤال 17

A triangle has angles of 110 degrees, 40 degrees and 30 degrees. What is its angle classification?

  1. right-angled
  2. acute-angled
  3. scalene
  4. obtuse-angledپاسخ درست

The largest angle measures 110 degrees, which is more than a right angle, and that alone makes the triangle obtuse-angled. Looking only at the two small angles suggests the acute classification, but a single angle above 90 degrees settles the name on its own.
